What specific app were you using that caused the GPU hang?  Also if this is a
regression can you biect?

No specific app (not counting KDE desktop effects). If the problem is the
kernel it's a regression because I didn't have any problem with -rc5.
Unfortunately it's not easy to trigger the crash so there is no chance to
bisect given how busy I actually am.

Is that stop poisoning the GART TLB?

Whatever - it could be a separate issue, but I am now getting sort of random
crashes on your drm-next-3.16 with my pitcairn.

I am stable on deathsimple 3.15 fixes + hdmi patches.

It applies to all asics from rs600 forward.

Ahh, in the meantime I've now built with 

optimize SI VM handling + use lower_32_bits where appropriate reverted - the
latter just so I could revert the former.

I'll see if I am stable over the next couple of days like this.

Spoke too soon, I just locked. Wasn't quite the same as before in that screen
stayed on displaying normal rather that off/on + junk.

Wasn't doing anything GPU related (accepting I always am with glamor), was
doing a big compile, so memory pressure I guess.

Also just add to the mix, after thinking I was stable yesterday I upgraded gcc
and updated llvm and mesa so they were different in several ways, though I
haven't rebuilt kernel.

First of all: excuse my bad english.

I have the same problem with my HD 7950; using hangouts, playing Left for Dead
2, or watching a flash video my screen goes crazy with vertical lines or grey
fog. Started when i upgraded to testing repo (Archlinux) and downloaded the
newest linux-firmware package, who includes TAHITI_mc2.bin. I suffered this bug
on kernels 3.14 and 3.15. For now, i am using 3.15.1 kernel, and the old Tahiti
firmware, and it seems stable.

You're right, i was compiling too when it crashed. Nothing GPU related anyway.

I got another lock last thing, this one was "typical" happened when closing
seamonkey, this is the third time closing it has locked. Of course it doesn't
do it if I try. I must be using gl someway/sometimes, as the last thing I see
is the xterm from where it was started and there is a mesa message about
default setting for s3tc being overridden by env (and that's not by me - I
don't have drirc anywhere).

I think this is going to be a pain to find - I just tried reset --hard onto 

 add large PTE support for NI, SI and CIK v5

that failed to resume from mem 1st try, though it wasn't locked. just corrupt
(mouse cursor large block of junk, fluxbox desktop black, but toolbar still
visible) so maybe a different issue fixed by a later commit. I could SysRq -
the log was normal.

Well I haven't tried without it, but I have so far failed to reproduce this bug
on a slightly older 3.15 drm fixes also using TAHITI_mc2.bin.

Did you test a new kernel with the old firmware or an old kernel without the
new firmware patch?  It could be some other change if you did the latter.

3.14 or 3.15 + New firmware = Crashes

3.14 or 3.15 + Old firmware = No problems!

OK forget it. It's not a firmware related problem. I had this bug with old
firmware on kernel 3.15.1. I resized a flash video window (vdpau accelerated)
and lost my screen.

> This bug is still present in 3.16 rc4, and 3.15.4.

This sounds exactly like the bug I talk about in Bug #80141. I'll mark my bug
as duplicate of it.

Could Mesa commit c8011c1885003b79c9f0c6530e46ae6cb0e69575 have anything to do
with what made 370184e813b25b463ad3dc9ca814231c98b95864 need to happen? Think
that could be re-enabled for our GPU's now or not?

Also, would the geometry shaders have any effect on our GPU's as Mesa just
patched a couple leaks on those.

These 2 fixes look like good ones fore this problem, as this problem was very
random and sporadic, and that is the definition of a good, small leak.

I can reproduce this bug, using mesa-git repo from Archlinux under kernel-lts
3.14.12. Unigine-valley engine ALWAYS crashes my display when 3D scene starts.
If i use normal mesa (10.2) i can run ungine valley OK! But the bug is always
present. Like i said in my previous posts, watching flash content increase the
chances that the bug appears.

On my machine i have no flash player installed but it increase the chance for
this bug too on watching HTML5-Videos(qtwebkit with gstreamer).
Unigine Valley is always crashing with black screen and GPU hang.
Unigine Heaven works but with white screen(the FPS are visible), but im not
sure if it have something to do with this bug.
Using Linux 3.16-rc4 and mesa-git

Tried this on alex drm-fixes-3.16-wip with my R9 270X and it didn't go well.

When doing nothing I am getting errors (attached), later I was transcoding some
vids so I guess memory pressure, and then I managed to lock the screen by
trying to use uvd. I could SysRq OK - so different for me from before in that
respect.

Applied to 3.16-rc5 and after about 12 hours, most of which I've been watching
youtube videos, all is well here. Also gamed fine, lots of screen switches and
movement. I'll report any crashes/errors I encounter, though. But this is much
more stable for me, no problems at all.

Both of these patches together on top of a 3.16-rc5 kernel make an unbootable
kernel for me. It has a null pointer dereference somewhere very early along the
lines of loading and setting up everything.

This is with only the 3.16-rc5 patch without fix-ups, which was working okay.
But when I clicked on the top-right of facebook to open up an event, it went
out just like old times. But if you see from the time, it had a good run this
time for sure. Youtube/Video players in general never crashed it once. I have
the fixed kernel building now so soon I'll jump on the fixed one, it looks like
code related to this has changed (Error message output a little different.) so
I'll try it out.

Possible fix v3.

Updated and largely simplified patch.

I'm running the third piglit test with it now and so far the system seems to be
stable.

Built, testing. Played youtube videos, chrome, multiple tabs, all while playing
Portal 2 and not a single hiccup on the output, outside of the casual VBlank
update problems I see you guys working on for 3-17. I did get a crash on the
old patch, as said, but we'll give it more time and I'll post any negative
results. For now, this is much more stable than before, though.

Just had a crash happen, was opening a Yahoo page. Very normal to crash on it
TBH from the old version too, but it shows that this patch may only delay the
problem, not be an actual fix. I don't really know what to say about it, same
old same old. :/

I tried to run piglit with all tests and everytime(I tried 3 times) i get a
blackscreen and the System hangs. I dont know the usage of Piglit so i cant say
on which test the GPU hangs.
It looks like the same bug which also appears randomly by watching
videos/flash.
I used the latest patch(v3).

Just posting another crash here. This one was caused, possibly by youtube as it
was on in the background, but clicking on a facebook chat, it just lost it. So,
there it is.

I am using now vainilla 3.16 rc5 kernel, xserver 1.16, llvm 3.4.2 and latest
mesa-git code. I had another crash, but this time i didn't lose my screen, I
could "dmesg" and saw a lot of:

radeon 0000:01:00.0: failed to get a new IB (-35)

Then I could resuib my computer.


--------------------------------------------------------------------------

Now when I am trying to run unigine-valley I don't lose my screen like before,
but i had this error:

Been running (not piglit) for a few days now without crashing.

I see it and a couple more fixes are now in agd5f drm-fixes-3.16-wip, so will
try that.

I can confirm that the bug still isn't fixed. But, it does seem to be much more
delayed now, though. I can run youtube for a while, but now Chromium seems to
crash it more often in general. Been running for a few days, have had at least
4 crashes. All with about the same fail logs as before. But as side, there's a
few VM and IB fixes extra in the 3.16-wip and 3.16 branch, so I'll wait until
those to care about this problem more. :)

Your Youtube / Chromium issue is probably separate and should be tracked
somewhere else. This report is about a stability regression in 3.15/6-rc
kernels, which seems to be addressed by Christian's fixes.

Yeah, agree. Your log doesn't show any VM faults at all.

That looks more like a userspace problem triggered by some Chromium operations.

[Bug 79980] Random radeonsi crashes

thanks for all the fixes !

currently using
http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.17-rebased-on-fixes
and it looks pretty stable so far (radeonsi, R9 270X)

even with 3.14.14 there were some (pretty seldom) but occasional crashes of X:

vanilla 3.16-rc6 was pretty much unusable (X + box hardlocks)

and especially http://cgit.freedesktop.org/~agd5f/linux/?h=drm-next-3.17-wip
(*without* the fixes) had dozens of gpu crashes yesterday evening/night which
were recovering (probably thanks to radeon.hard_reset=1) without crashing X and
hardlocking the system:


ring 0 stalled for more than 10010msec GPU lockup
waiting for ... last fence id ... on ring 0
GPU softreset ...

and

(WW) RADEON(0): flip queue failed: Invalid argument
(WW) RADEON(0): Page flip failed: Invalid argument



currently still running with radeon.hard_reset=1 - but that probably shouldn't
be needed anymore


best trigger for those occasional crashes was using chromium/chrome, watching
videos on youtube, switching apps via alt+tab (using an composited desktop with
compiz-fusion 0.8.8) and from time to time opening up gmail (which, if I
remember correctly would cause the gpu to crash at least twice of these
countless times yesterday)

crash during watching of a flash-video on youtube

video during crash was: https://www.youtube.com/watch?v=9QIlB3ZVJes

before that: https://www.youtube.com/watch?v=fMKe89zcvHU

and before that: 1 video in 1080p, 3 videos in 720p (mainly slowly moving
classical music, not sure if the type of the video's content [slow, fast-moved,
etc.] makes any difference)


like mentioned in https://bugs.freedesktop.org/show_bug.cgi?id=81612 will try
running with zswap & zram disabled,

but the frequent crashes on drm-next-3.17-wip also occured with zram, zswap
disabled

this is the Xorg.0.log after X finally crashed after all the recoveries and
xdm/slim/startx couldn't be successfully launched up anymore (it stayed in VT)

it's basically the same behavior like with drm-next-3.17-wip - only, that it
this time took longer until X couldn't be started up anymore

I think the main issue this bug was for (VM page table stability regression) is
fixed at this point.  The remaining issues seem to be due to video playback as
that seems to be the common trigger in the last few comments.  You might try
not using vdpau for video playback to see if that helps to narrow it down. 
Someone should probably open a new bug for the videoplay back stability as this
bug is starting to get unwieldy and has become a dumping ground for anything.

even with those last lines from #68 ?

I've suspected for some time, that it must be related to videoplayback and uvd
- so it should improve with vdpau disabled, right ?

but those last lines got me thinking that it could be something else

in the end (after those recovery attempts)

triggers (where the screen turned black) were

- switching between programs (alt+tab)
- simply entering text in a note (gnote) [at least twice]
- ... others I currently don't remember

not sure but the flash version in chromium/google-chrome isn't using vdpau at
all, right ?

can't remember having viewed any video in a video-player accelerated with vdpau
during those crashes (not even before)

so it's not related to vdpau, at least in my case

This bug was originally about a stability regression due to some GPUVM changes
in 3.15.  If 3.14 is stable for you but newer kernels are not, then it may be
related.  Otherwise, it's probably another issue.  See bug 81644 about
stability issues with Chromium specifically.

To be sure start chrome with the env VDPAU_TRACE=1 and play something, there
will be lots of debugging to see if it does use it.

I've tried quite hard to crash and so far failed, but then I am using
seamonkey, and it seems I am also a few commits off head now.

Alex I didn't use vdpau when playing back, also I got an X freeze even without
playing back anything: I was just starting Android Studio, PyCharm and Netbeans
(I often get freezes when starting these editors).

unfortunately 3.14 also isn't entirely stable it mostly is (99%) but here the
problem is that very very seldomly X simply crashes, gpu doesn't simply turn
black and recovers, so important data can be lost (when being worked on) -
couldn't pinpoint the reason yet - the gpu just "reboots"

no additional error messages dmesg or Xorg.0.log as far as I know

can't say anything about kernel versions prior to that since this card is still
a few days old


gcc 4.9 also couldn't be the cause, at least with 3.16-rc* kernels and
drm-next-3.17-rebased-on-fixes, since I've already added the patch manually and
the kernel also isn *NOT* compiled with -Os (optimize for size)


it seems to be more of general instability going towards 3.15 and 3.16 - but
who I am to ask, I'm just a enthusiast user :P


having read about stability issues with the new firmware somewhere

how could I test and revert to the old firmware ? would it still work ?

simply removing the PITCAIRN_mc2.bin (e.g. for the R9 270X) and leaving the
other PITCAIRN files in /lib/firmware ?

the graphics driver is loading as a module and not compiled into the kernel or
included in initramfs

I'd really like to upgrade to 3.16-rc* due to recent changes (especially in
connection with Btrfs)

an option to disable UVD entirely would have been nice (when still using 5850
and during the new introduction of DPM there was a patch which offered a module
parameter to turn it manually off) - would that be an option to further
troubleshoot this issue and to exclude UVD from the list of potential causes ?


Thanks

output of Xorg.0.log during uvd-test with DVD watching in fluxbox via smplayer

mark the "extra" explicitely set settings:

[   253.915] (**) RADEON(0): Option "EnablePageFlip" "off"

[   253.915] (**) RADEON(0): Option "SwapbuffersWait" "on"

I read about commits from 3.14 to 3.16-rc* that mentioned pageflipping changes
but disabling that didn't make a change




*before* watching the DVD

I did another test

and accidentally watched a short portion of a HTML video on youtube with
chromium (actually only had intended to read lkml, but there was a reference
link and didn't mention that it was a video /facepalm), did some browsing, had
gnote running (and some more which I currently don't remember)

adobe flash was explicitely turned *off* via about:plugins

and X hardlocked while playing music (and mp3, via audacious) & browsing via
chromium


so at least in my case more and more signs seem to lead towards bug 81644
(https://bugs.freedesktop.org/show_bug.cgi?id=81644) and that chromium + html
video; or chromium and all sorts of video (vdpau doesn't apply here ?!)
triggers instability & (hard)locks

Well I just tried drm-next-3.17-rebased-on-fixes and it died as soon as fbcon
loaded. Screen full junk and an oops logged.

I have got the new firmware (unless there's an even newer one) and have booted
into the other 3.17 before - but it eventually crashed due to missing fixes.

Please file a new report for that, it's nothing to do with random crashes in X.

When did you download it?  The header format changed last week and I uploaded a
new version.

does this apply to PITCAIRN gpus, too ?

I only see firmware up to April (PITCAIRN_mc2.bin)

kindly link to the new firmware files so that I can update to it, too



update:

posted new information concerning this case (or the issue with chromium) in

The new firmwares have lowercase names so you can keep the old ones in place
for kernels < 3.17.

the trigger still seems to be chromium & the whole box hardlocks ...

both firefox & chromium had hardware acceleration/webgl disabled

Still present in the final 3.16 kernel. This bug is really crazy. I have a lot
of hard lockups playing Age of Empires HD using windows steam. I can't provide
any log or debug info because my machine die completely.

My hardware is: Gigabyte HD 7950, using HDMI output on Archlinux + KDE + Mesa
10.2.5 + xserver 1.16.

make sure you try out the very latest & greatest

http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.17-rebased-on-fixes

with userptr support

these changes are supposd to be performance-enhanced improvements (only ?) but
also seem raise stability for me ( bug #81612 ):

information on this:
http://lists.freedesktop.org/archives/intel-gfx/2014-February/040513.html


I'll go ahead and test other user-cases, see whether those are also stable now

--- Comment #92 from Chernovsky Oleg <adonai@xaker.ru> ---
I've successfully reproduced this bug 

I'm on 3.16 kernel, mesa 10.2.5.

I start Qt5 QtCreator (as I know it uses OpenGL acceleration for some QML
elements), then I start any 3D-demanding app (like one of Valve's game titles).
After that I close app. And when I close QtCreator, this bug occurs, total
system hang, ring 0 freezes and does not wake up on soft reset.

Where should I look at to fix it? I assume it hids somewhere in GPUVM? (or is
it needed anymore or is it already fixed?)

Is there some way to debug this?
Debug messages from the kernel/mesa/whatever to activate to find out what goes
on with the radeon driver.
Some /sys files to monitor or something?

Please let us help you fix this bug but for me at least it was always a
complete deadlock with nothing in the logs to indicate what went wrong.

Unrelated.  You are seeing bug 82162 which is already fixed.

Hey, my system is running nearly crash free for three days now with Linux 3.17
RC1. The crashes were related to VLC and VDPAU and something got stuck but my
system feels pretty stable now. If you are on Arch Linux compile linux-mainline
from AUR and try for yourself (don't forget updating GRUB).

3.17-rc1 + drm-fixes seems MUCH more stable than ever. I will let you know if
things keeps going on well.

Some userspace component is generating an invalid command stream.  Probably a
bad packet count somewhere.

So, is this bug finally fixed? I saw some activity, but was it a real fix or
only a workaround?

I think thus bug has become largely useless.  It's become a general dumping
ground for any sort of problem with radeonsi.

3.17 rc1 and 3.16.1 are still affected by this bug, but they are more stable
than previous kernels.

The original bug wasn't fixed in 3.16-rc but it seems fixed in 3.17+drm-fixes.
I will let you know after a couple of days, I'm really happy I can use radeonsi
once more. With 3.16-rc I had crashes after a few minutes of usage.

Yep. I tried to repeat previously described crashes (including my own) on
3.17-rc1 with your drm-fixes branch and failed. No gfx ring lockup anymore.

Well that was the problem: A couple of different things!

We have an long outstanding issue with TLB poisoning, a couple of bugs related
to dynamically allocating page tables and I think one or two userspace issues
mixed into a single bugreport.

Thanks, Christian, so I assume, all those issues were fixed and TLB poisoning
was workarounded for now?

I'm asking because I'm currently digging through the source trying to figure
out the full picture.

Here is drm-fixes and yes, it will be part of -rc2:
http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-fixes-3.17

Unfortunately I've been too eager to declare drm-fixes stable because I just
got an X freeze:
[139998.633243] traps: chrome[11324] general protection ip:7f8f8f1790b0 
sp:7fffba3d5610 error:0 in .radeonsi_dri.so._portage_merge_.20817
(deleted)[7f8f8ef8c000+5de000]

I was simply running an "emerge --sync" while browsing a couple of simple web
pages.

Any chance to fix this? If yes I'm willing to open a new bug for this.

I've been stable for some time now using seamonkey, but than I use flashblock
and don't usually use it for vid. Saying that I have deliberately tried and
failed to crash playing vids since this bug started.

I think there's another bug for chromium issues.

My specs (was in a hurry yesterday):
HD7950
Core2Quad
Kernel 3.16 (openSUSE Factory, x64, KDE+desktopeffects)
Rest from git (mesa, llvm, ati, xserver)

did not test chrome, but firefox and its old flash (11.2) or steam games never
gave me x-crashes or lockups on radeonSI. Also earlier kernel versions
(openSUSE Tumbleweed) made no problem.

I can very quickly, almost deterministically, hang the GPU (radeonsi, Cape
Verde) with the following command:

> LIBGL_ALWAYS_SOFTWARE=1 mpv --fs --vo=opengl:sw /path/to/some_video

this works on both 3.16.0 and 3.17rc3. Try seeking, it often happens directly
after a seek. In most cases, the hang is unrecoverable and crashes the kernel
after some "atombios stuck in a loop" messages. Very strange indeed, software
rendered glxgears doesn't cause this.

Can anyone verify? A somewhat reliable test case might be a good start to
finally fixing this.

Well this is interesting, so you're saying that using software rendering on the
client side can crash the GPU? That only leaves glamor and maybe the compositor
as the only one using the hardware driver.

I also can't reproduce with pitcairn (R9270X)

On agd5f drm-next-3.18-wip, git mesa,llvm,ddx,glamor. Xorg couple of months
old.

Tried with mplayer and 2 versions of mpv.

Running fluxbox, so no compositor.

Other differences - I guess mesa/llvmpipe uses different sse for me on older
CPU (phenom II x4 965).

Screen res? I am testing 1920x1080@60Hz.

Radeon 8550g/8670m - doesn't get passed login screen with 3.17-rc3. At least in
rc1 I could get to the desktop but then it would almost immediately hang.
(distro: Ubuntu 14.04 standard + Gnome 3.2).

Works like a charm on kernel 3.14*

This is 100% reproducible: just start 3DMark2003 with a gallium nine enabled
wine (and mesa of course) and it will crash your whole system:

When radeonsi in the right mood (I guess something triggers an higher
instability) then Chrome becomes completely unusable: opening simple urls
without videos is enough to trigger segfaults. The system hangs for a few
seconds and then it keeps working normally until the next segfault.

Kernel is drm-next-3.18, but I had similar behaviour with any kernel >= 3.15

I get several crash every day.
Right now I'm using the kernel 3.17 with mesa git from ~lcarlier repository
(arch linux + kde4) on my radeon hd7970. Switching to stable kernel and mesa
don't change the situation. I don't know if this is the same error but I leave
my dmesg log from latest crash. The system stop responding and the monitor
output garbage. Sometime I can switch to TTY to reboot. Most of time I can't.

With the kernel 3.17 rc7 the crashes are a lot more frequent than 3.16.4

--- Comment #137 from Jacob <jacobsvenningsen15@hotmail.com> ---
About three months ago I stumbled upon this very same bug. The system will just
totally lockup, and I pretty much have to force restart the machine. It seems
to happen on any kernel newer than 3.13, least in my case.
I've tried with mesa 10.4, 10.3, 10.2 and even 10.1 and nothing seems to fix
the problem. It was only when I started changing the kernel versions, that I
finally found 3.13 to be stable.

Been using the Oibaf PPA and Linux 3.13 for the past month and a half, and I've
not experienced a single crash, but when I try any new kernel releases it won't
be long until I experience yet another system lockup.

The other day I noticed that the onboard video (i5-3570K - HD4000) was enabled
after a BIOS upgrade. By disabling it the radeon driver crashes have stopped. I
write only because it could be of help to someone.

Can you bisect which change between 3.13 and 3.14 caused the instability for
you?

I've only downloaded kernel images as .deb files from
http://kernel.ubuntu.com/~kernel-ppa/mainline/
How would I go about bisecting which change caused the instability?

In the bios. In my case (asrock z77 extreme6) I have to disable the entry "IGPU
Multi-Monitor"

Unfortunately it doesn't help, on the contrary I just got a new instability
world record: it crashed in *KDM*! Yes of course, I didn't even had time to
type my username!
I never checked GTX 970's price so often: one day or another I will find a good
offer and I will say goodbye to radeoncrash forever.

Same issue with my HD 7770 on 3.16 and 3.17 (much often). Even trying to write
this comment here cause crash. So I am unable to write more details on this pc,
because of time to crash is reali tiny :(

Perhaps you should revert to 3.14 LTS until this issue is fixed. I don't have
any issues running 3.14 with my 7950.

Same issues with my OLAND card here.
Archlinux, Mesa 10.3, Xorg 1.16.1 and Radeon 7.5.0.

Kernel 3.14.20 is still stable, 3.16.X and 3.17 may run for approx. 1hr and
finally crash during normal desktop usage (Gnome 3.14 + Browser + ...). Didn't
check 3.15 recently.

Sooner or later someone needs to bisect that sucker! :)

IMPORTANT

This was my first message in this bug report: 

I have the same problem with my HD 7950; using hangouts, playing Left for Dead
2, or watching a flash video my screen goes crazy with vertical lines or grey
fog. Started when i upgraded to testing repo (Archlinux) and downloaded the
newest linux-firmware package, who includes TAHITI_mc2.bin. I suffered this bug
on kernels 3.14 and 3.15. 

--------------------------------------------------------------------------

In Archlinux i was stable with kernel 3.14, and the problem started when i was
using the new firmware. I thought that the new firmware was the cause of this
bug, but NO, because i had the same bug using the old firmare, so this bug it
was caused by one of this radeon commits backported to kernel 3.14.6 (the first
kernel using newest firmware). I am 100% sure.

I've tried using different kernel versions the past few days and I've failed to
trigger the crash with any kernel prior to 3.15-rc3. Today after a few hours of
used, my system just locked up again and my screens went black, forcing me to
reboot the machine, same thing I've experienced with 3.16 and 3.17 so I believe
this is where the bug originated.
However, it seems like when I booted up, nothing has been written to kern.log
nor does any errors show up in xorg.log, and dmesg shows me nothing.
I got the image from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc3-utopic/ which also
shows what changes were made to this release.
The issue might have originated here, but it could very well be that I've
missed something.

I've just compared the git messages from your link and from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc3-utopic/CHANGES and it
seems like the commits made to drm/radeon, are the only commits these two
kernel versions have in common.
Only seven of them are part of 3.15-rc3, which crashed on me yesterday, so it
would seem like the crashes are caused by one of those commits

Yeah, it just crashed on me again. So I was just lucky. I also tried disabling
dynclks and dpm, no effect. What I did differently yesterday is I had very
litte browser (Debian Iceweasel) usage. Today I had some Youtube running when
the crash happened. In fact the crashes happen most time when whatching stuff
on Youtube, i.e. when Iceweasel uses vdpau through gstreamer. I now removed
mesa vdpau drivers. I will report back if this changes anything.

The last image I tried was 3.15-rc2, which didn't crash on me during 18-hours

Can you try 3.15-rc2 again for even longer, to make sure it wasn't just luck?

If it's consistent, it would be really helpful if you could bisect between
3.15-rc2 and 3.15-rc3.

I'll do that; try rc2 for a couple days, see if I can get it to crash, then try
rc3 again to see if I can crash that again just for good measure, then do a
bisection between the two, if rc2 turns out to be stable and rc3 does not

--- Comment #164 from Jacob <jacobsvenningsen15@hotmail.com> ---
So after testing 3.15-rc2 for about 3 days without any crashes, I decided to
once again test 3.15-rc3 to see if it would crash on me again, which it did.
The OS just stopped responding to anything, then my monitors went black, just
like it has done for me on 3.16 and 3.17 as well.

I ran a bisection between the two releases, and the result was the following:
Bisecting: 120 revisions left to test after this (roughly 7 steps)
[3fe89d2e768792a924d3c1e9310ba0b4448cb78e] Merge tag 'fixes-3.15-rc3' of
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Seems weird that arm got anything to do with this issue, but even after running
"git bisect bad" until the end, it doesn't pick out anything committed to
drm/radeon.
Nonetheless, I compiled the kernel, and I'll now test it to see if it'll crash
or not, then run git bisect bad until the kernel gets stable once again.

I'll report back if I either manage to compile a kernel which is stable, or if
I don't

After upgrading to kernel 3.17.1, these GPU hangs/crashes still occur, but now
it doesn't hang the whole machine any more. Sometimes it recovers from the GPU
hang completely, sometimes it just drops me into a text console. Thanks, that's
an improvement.

I am using Radeon R9 270 on Arch Linux.

That's not the result but just an early step of the bisection. :) As the above
says, Git estimates that you'll need to test around 7 more kernels before there
is a result. BTW, make sure to only run 'bisect good' after you've tested a
kernel long enough to be sure it's not affected by the problem. If you mark a
commit as good which is actually bad, the bisection will fail.

if this helps any, I've been seeing the same error on my gentoo box, its near
constant on 3.16+ kernels within 2 or 3 min of loging in X but, ive been seeing
it very rarely (once every few hours) on 3.14.22 but still seeing it, and I
never seen it happen on 3.14.19

Could you test 3.14.20 and 3.14.21, to see if the issue also occur in any of
those, then do a bisection between the first version where the crashes started
to occur, and the version prior to it?

On my system with 3.17+ sometimes it takes days to crash while sometimes it
crashes after a few minutes. Only 3.15 did *always* crash in a couple of
minutes. I remember 3.15-rc1-pre didn't crash, so the bad commit should be
somewhere around 3.15-rc0 and 3.15-rc2.

Takes about a couple hours for me to crash 3.15-rc3, "sadly" not minutes.
3.15-rc2 didn't crash on me,  so I'm currently doing a bisection

Considering the crash occurs within an hour or two on the last kernel, but only
occurs every few hours on 3.15, it makes you wonder if the two issues are even
related.
Nonetheless, I'll report the result from the bisection once I got it

Kernel 3.15 has some known VM issues which are only fixed in 3.16. Independent
of that I think we indeed have multiple different issues that seems to be hard
to distinct.

In general you can split the issues into two categories one is with VM faults
in the logs and the other ones are without.

Seems the one I'm bisecting for now would be the one without then.
Whenever it crashes, I get nothing in the logs at all. Nothing in dmesg, in
xorg.log or in the kern.log. Nothing at all

The "supposedly" random crashes I encountered with 3.15-rc3 weren't really
random at all. I came to a somewhat sad realization that only one application
actually crashed with it, so the bisection has mostly been a waste.

I've personally been stable on 3.14.20, and according to DJ Dunn, the issue has
now hit 3.14.22, so I'm gonna check 21 and 22 to see if it crashes for me as
well, and this time make sure it's application independent.

I've seen that mentioned before, but the answer is always the same: Please
bisect Mesa.

Sorry, I do not know how to do it. But these are the changes between RC1 (still
crashing) and RC2 (stable):

 drm/radeon: reduce sparse false positive warnings
 Revert "drm/radeon: drop btc_get_max_clock_from_voltage_dependency_table"
 Revert "drm/radeon/dpm: drop clk/voltage dependency filters for SI"
 drm/radeon: initialize sadb to NULL in the audio code
 drm/radeon: fix speaker allocation setup
 drm/radeon: use gart memory for DMA ring tests
 drm/radeon: fix vm page table block size calculation

I am not an expert, but probably: drm/radeon: use gart memory for DMA ring
tests; could be the good commit.

Search the web for 'git bisect howto'. One gotcha is that you'll need to run
'git bisect good' for bad kernels and vice versa, because git bisect can only
isolate good -> bad transitions.


> I am not an expert, but probably: drm/radeon: use gart memory for DMA ring

That should have no effect once the driver is initialized. None of the changes
between rc1 and rc2 seem like obvious candidates.

https://wiki.ubuntu.com/Kernel/KernelBisection
This guide helped me. Might help you too.

In short, you just have to clone the Linux repository, run "git bisect start
<BAD> <GOOD>", then compile the kernel and test it.
If it crashes, then run "git bisect bad", and recompile.
If you think you've tested it long enough and the version is stable, then run
"git bisect good", and recompile.
Continue to do so until no revisions are left to be tested

It's random for a reason, it acts like a buffer over run or leak or something
that isn't easily produced, as it changes how often it happens every installed
package. But I've had worse luck on 3.18-rc2, it's just my install is more
prone to it this build where it seems others haven't crashed yet, but give it
time. Make sure you run HTML5 youtube for an hour or so. ;) :)

This is strange because 5 days ago i was starting to use intel graphic card
because i had a lot of lock-ups with 3.17.1 and 3.18 rc1 kernels. When 3.18 rc2
was launched i returned to radeon driver and this bug disappeared under 3.18
rc2, but now i am using 3.17.1 and it seems stable... Maybe this bug is a mesa
problem, and not a kernel problem. Mesa 10.3.2 arrived to archlinux 3 days ago.

Changes from 10.3.1 to 10.3.2:

Brian Paul (3):
      mesa: fix spurious wglGetProcAddress / GL_INVALID_OPERATION error
      st/wgl: add WINAPI qualifiers on wgl function typedefs
      glsl: fix several use-after-free bugs

Daniel Manjarres (1):
      glx: Fix glxUseXFont for glxWindow and glxPixmaps

Dave Airlie (1):
      mesa: fix GetTexImage for 1D array depth textures

Emil Velikov (3):
      docs: Add sha256 sums for the 10.3.1 release
      Update VERSION to 10.3.2
      Add release notes for the 10.3.2 release

Ilia Mirkin (4):

I don't think so. I try tio downgrade mesa, linux-firmware and lots of other
packages, but even with vdpau vlc, html5 youtube videos or flash videos I am
unable to frozen my system again (I really try it hard all day). It must be
some HW problem or some wierd HW state or something completly different.

I guess it is possible there are many different crash types. I'm still crashing
left and right. Is everyone else still stable? If so, looks like I'll leave you

Unfortunately, this bug has become a dumping ground for any kind of stability
issue with radeonsi so I'm not really sure how useful it is anymore.  I suspect
there are actually multiple issues that are now all mixed up.

What's the way forward? Shouldn't it be up to the developers to try and make
sense of the reports and split up the bug entry appropriately?

Should there be one report per affected user, or is there a better way to group
them together?

Christian König from comment #175 made one suggestion, is that what we should
be doing?

Assuming my issue is separate, and your fixes were fixed, ever since my issue
was the only issue pertaining to random crashes, mostly by video players/web
browsers, it seemed the AMD guys never could reproduce it. After some time with
nobody else on the bug report, a few appeared with the same problem, and
reported the exact same results. Somewhere after that though, I think there
were more "Random crashes" bugs. I'd bet the ones who joined in a little later
have the same bug as me, the more current random crashes are probably not the
same though.

Maybe we should kill these reports, and make a couple with titles more
appropriate, funnel people there, and start over. :)

There are other bug reports related to stability issues specifically with
chrome, firefox, and video playback in certain cases which may not be related. 
Those bugs may be better fits depending on the exact nature of the issue you
are seeing.

I had the very same behaviour with any 3.17+ kernel: sometimes it doesn't
crashes for days, others it crashes multiple times per minute. It doesn't
matter what you do, it just crashes (even starting your desktop environment is
enough sometimes).
I will probably buy a Nvidia GTX 970 while waiting for the new unified driver,
then I will try the open source path once again: hopefully having the
proprietary driver using the very same kernel code will force AMD to take
stability into higher consideration.

Not that it is very prominent, but I also plan on switching to a 780 Ti or
similar, if the AMD guys can show their management how many people are not only
going to hurt the company, but support the competition it might show AMD it's
worth it to get you guys more help over all.

Yeah, on both occasions, I was trying to write a message in a forum. (Chromium)

If it's happens mostly with chromium, it may be bug 81644.  When you say crash
what do you mean?  Segfault?  System hang?  GPU hang?  GPU page fault? 
Something else?

My bug is not Chromium related. 4 months ago, my browser was Firefox and i had
the same bug. Always is the same behaviour. Sometimes with videos, or games,
flash content... It´s totally random.

I think it happens often when I click anywhere or i resize a windows with vdpau
content, then my system is freezed 5 seconds (I can move the mouse, but the
windows or programs are not responding) after 5 seconds, my screen shows
garbage like this:  https://bugs.freedesktop.org/attachment.cgi?id=101226  or
my monitor turns off completely. Sometimes i can reboot with reisub, sometimes
i need a hard reset. Some months ago i posted a picture of my dmesg output

I believe Firefox and Chromium both suffer from the same issue myself, we've
been treating it that way at least, and Firefox users have never reported any
changes different with patches and updates, so I believe the same issue is
being talked about as with Chromium. I think it has to do with video being sent
to the GPU at all, which with RadeonSI and any modern browsers, any accelerated
browser probably will have the same problems.

We are doing that all the time. However, users tend to focus too much on some
symptom(s) they have as well and ignore any differences. It's understandable,
but unfortunate.

I can't think of anything better than that. In general, it's much better to
track things separately. Once several unrelated issues are mixed up in a single
report, it's very hard to untangle and keep track of it.

So *TELL* users that clearly, to make individual bug reports. Close this bug if
necessary. Direct your users instead of going "oh well, users can't report bugs
and we can't do anything about it".

When I was beginning to see these issues, I asked around in #radeon whether I
should report a new bug, and I was told to see this bug instead. Of course that
was another misled user.

I looked back through kern.log and found the last time I encountered a crash,
which happened to be with kernel 3.15.10 from the Ubuntu repo.
That crash seemed to have been caused by dpm:
[drm:si_dpm_set_power_state] *ERROR* si_set_sw_state failed

The 3.15.10 version isn't part of the source, so I instead looked through the
list of changes and found that the last set of changes made to drm, landed in
kernel 3.16-rc6.

So I installed the rc6 image and has now been running it for some time, but ran
into yet another issue, which is unrelated to this bug.

[ 6533.114483] alloc_contig_range test_pages_isolated(1bc800, 1bca8c) failed
[ 6533.114492] alloc_contig_range test_pages_isolated(1bc800, 1bca8d) failed
[ 6533.114500] alloc_contig_range test_pages_isolated(1bc800, 1bca8e) failed
[ 6533.114506] alloc_contig_range test_pages_isolated(1bc800, 1bca8f) failed
[ 6533.114511] alloc_contig_range test_pages_isolated(1bc800, 1bca90) failed
[ 6533.114516] alloc_contig_range test_pages_isolated(1bc800, 1bca91) failed
And so on.
It pretty much causes frequent 2-5 second hangs, even while I'm writing this
message. Just moving the cursor, causes such a hang. Changing workspace and the
hang lasts 40 seconds.
In other words, bisecting the dpm issue would be very difficult, since I would
more than likely run into this issue as well.

The last change made to drm/radeon/dpm were merged into 3.16-rc1, and it only
affect si hardware.

Suppose this issue could be moved to another bug entry, if it hasn't already
been fixed.

Jacob, please report a separate bug about your symptoms.

Should the two bugs resolved as "duplicate" be de-duplicated then? Bug 80141
and Bug 82886.

Pitcairn is Southern Islands, just like Cape Verde and Tahiti.

I reopened 82886, but Aaron already has his own report (about Chromium, but it
may or may not turn out to be the same problem).

I'll duplicate my Bugs to Bug #85647 to start over, I KNOW I have that bug at
minimum. I'll  stay off of other "Random RadeonSI" crash reports until we
resole it there.

--- Comment #218 from Sean Rhone <Espionage724@gmail.com> ---
Just a bit of feedback, but my 7850 seems relatively stable under Xubuntu 14.10
+ 3.18rc3 + Paulo's mesa PPA.

General desktop usage and web browsing over the past week resulted in no
crashes or GPU hangs, but I did have a slightly weird issue with fullscreened
flash video (while fullscreen once the player OSD disappears, moving the mouse
would freeze the video, but double-clicking it to un-fullscreen it was fine and
it played back normally).

Was watching a fullscreen video through Plex's web interface (I think videos
playback with HTML5?), I had a couple of GPU hangs (right term?) and restarts,
but they were really quick (black screen for about 2 seconds, then restore as
if nothing happened). If I recall right, there were about 2 or 3 hangs over a
37-minute period.

I'm using Google Chrome (not Chromium) 40.0.2202.3 dev (64-bit) with
--ignore-gpu-blacklist enabled. Just checking chrome:gpu, I noticed:

Of course since 'radeonsi: Disable asynchronous DMA except for PIPE_BUFFER' the

--- Comment #222 from fdb4c415@opayq.com ---
I would like to inform you I got the same problem. My box freezes randomly.
Keyboard is almost dead, mouse sometimes working (pointer moves, but cannot
click on anything) and usually I can only ssh into that box - to reboot it.
Sometimes Ctrl-Alt-F1 works and I can log in, but sometimes not. The monitor
switches repeatedly: no signal/black screen/no signal/black screen/...
In the log I can see quite similar messages:
radeon 0000:01:00.0: GPU lockup (waiting for 0x0000000000002258 last fence id
0x0000000000002255 on ring 0)
VM fault (0x04, vmid 1) at page 30481, read from DMA1 (61)

I have the latest debian test 64 bit installed:
Linux <host> 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt2-1 (2014-12-08) x86_64
GNU/Linux
and I have:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde
PRO [Radeon HD 7750 / R7 250E]

Is there any way to fix it?

There's a good chance that a newer upstream version of Mesa would help for your
problem, if not fix it completely.

For those still having problems, the kernel patches
http://lists.freedesktop.org/archives/dri-devel/2015-January/074968.html and
http://lists.freedesktop.org/archives/dri-devel/2015-January/074969.html might
be worth a try.

I applied
http://lists.freedesktop.org/archives/dri-devel/2015-January/074969.html on top
of kernel 3.18.4, and got:

radeon 0000:01:00.0: GPU fault detected: 146 0x0008080c
radeon 0000:01:00.0:   VM_CONTEXT1_PROTECTION_FAULT_ADDR   0x00000000

VM fault (0x0c, vmid 4) at page 0, read from 'TC0' (0x54433000) (8)

(following by an unsuccessful attempt to unwedge the GPU, but I guess the lines
above are what's really interesting).

This is with Mesa built from 8d2542fc9d5af4db355b67cc2a1ff2f413685a27 on a
bonaire xtx.

That's not a random crash but a reproducible one, probably a Mesa bug. Please
file a separate report for that.

Please report all issues you have as separate bugs! This bug mixes together
multiple issues and symptoms, so it's almost useless.

Also, it's worth noting that my crashes are pretty reproducible when running
Chromium without --disable-gpu if compton is running. Disabled compton and
haven't had any so far.

> Same symptoms with a Hawaii device (R9 290X).

There are no "same symptoms" in this bug report, it's a mix of multiple
different symptoms and issues. Please report a new bug for your problem.

Same with kernel 3.14.35-1-lts. Dota2 crashes everytimes within one minute
spectating a game and freezes the screen and keyboard. Networking works.

Please report a separate bug for your exact circumstances. This one is being
ignored by developers because there are many different causes.

I had this bug again :S 

Using KDE 5, i had 2 crashes when i changed speed animation in systemsettings5
- screens and monitor - compositor options. 

My system is Archlinux 64 bits, kernel 3.19.3 and mesa 10.5.2. I can't report
any dmesg or log, my system completely freezes.
