Xorg crash log of the system.

We have events pile up in the queue when the card becomes unresponsive. The
only place I've seen this happen besides one time in Counter Strike Source, are
youtube in Chromium running HTML5 video. More so when switching tabs to or from
the video when a lot of pixels on the screen changing. It does not have to be
rendering to crash, though, it happens off screen too. Otherwise no other
software triggers this bug nearly as consistently. I am attaching the XOrg
failure log. I'm on Mesa and firmware from the Oibaf PPA. 3.16-rc1 kernel, and
this is in every kernel for a while as far as I remember. From the log, you can
see the errors and how it says the queue overflows and the device is waiting
for something to happen, it more than likely is DRM related. The screen usually
goes out and stops rendering on the HDMI channel that I use, but sometimes
comes back with very badly botched video if it does, both cases result in a
100% unresponsive system, besides audio will usually continue to play until the
end of the video.

Hardware is an R9 270X Radeon card. I only use HDMI video output. I am using
the mc2 files even though they are not officially with any firmware package, I
added them when using the 3.15+ kernels. Any more info or anything else needed
just ask, I'll supply it.

Dmesg output.

I'm adding it for 3.15, currently trying to get this kernel to crash. Give me
time I'll test down to 3.13 and see if it's in all of them, but I'll need time
to find out which crash. I believe this has been a problem since 3.13 IIRC.
Before 3.13, the card was basically unusable, though, so I'm not going to test
down below that.

Crash information from card unresponsive crash. This one recovered from it,
though.

Just had a crash happen on 3.15 generic, I'm going to go back to 3.13 now and
see if I can trigger it on there from doing the same things.

New crash of DRM that led to kernel panic on 3.16-rc2.

(In reply to comment #2)
> Please attach your dmesg output.  What was the last kernel that was working
> without problems?

Added new file, I'm failing to find the kernel panic output with 3.16-rc2. It
mentioned something wasn't syncing correctly so it shut everything down. It was
a DRM bug from the read out. This is the log right up to before that happened,
and the time stamp for page flipping failing is the same as the output from the
panic so let me try to find it.

Thanks, but those backtraces are not useful for doing anything about the
problem: They just show that the X server's input queue is overflowing, because
the GPU is hanging.

Have you been able yet to find an older kernel where the problem doesn't occur?
With 3.15 or newer, might be worth trying the patches from

Okay no problem. I just had a crash happen and recover. What commands should I
run to get any useful log information for this? I'd post more logs, but it'd
just be more of the same basically. I'll fall back down to 3.13 for now and try
to get it to occur.

I don't have the ability as it is to apply those patches, although I could
probably figure it out. But I'm on 3.14. And I have no youtube problems, just
the old no audio over HDMI that I remember, so the first problematic kernel
with youtube is 3.15. Although 3.14 does have random crashes for other bugs and
such, but I don't believe they are the same problem and I also don't believe
they are in 3.15 either, just the one chromium youtube bug. My friend also has
a gaming linux rig very similar, different brands on the GPU, Mobo, but yet
same problems as me so I'm also going to say it's not a hardware problem too
just to verify if anyone was thinking that. Anything needs tested or if I could
even figure out how to make it happen easier than a random youtube video
problem, shoot me ideas so I can troubleshoot. Or help you guys out.

I need to test more, but I've been trying to make it crash, playing games and
youtube-ing the last few hours. I don't believe there's any problems with those
DRM patches applied. Applied just to a bare 3.15 from linus's git, and all is
well. I'll report any crashes here over the next few days if I get any, but
these seem to help. Great FPS in games to boot, just like the ones 3.15 did
bring by it's self. Just, more stable, like said in the comments of the
patches. I'll let this bug post know anything that comes about, but this seems
to work really well from the last 3 hours of using it. I'm on an R9 270X, like
said. So Pitcairn/Tahiti architecture here. But, all is well.

OKay, after some more testing, I have one bug still present in this version,
and also one problem which may not be related.

Bug #1: Cinnamon restarted when moused over the top panel. Made login sound,
and lost my BG preferences and icons went to GNOME-style icons. I don't think
this is related, but just noting it.

Bug #2: This was triggered by Chromium, when resizing the window/dragging with
the mouse on the top of the screen. This one particular time made the screen
jump, like I've also seen in Steam, but this one triggers a black scanline,
(very very rarely) accompanied by a slight (1px vertical) tear upwards at the
scanline the black line is on. They happen more towards the bottom and middle
of the screen, although they start at the top. It happened once every 10
seconds or so when it started, but now is happening 1-2 times a second
sometimes with multiple black lines in the same frame it seems. The black line
occurence is increasing as time goes on. This was VERY common in 3.14 kernel,
so the issue probably is just being put off by the new dri implementation I was
given to test, but still exists. I don't really know weather to make a new bug
report or not specifically for that, I don't really know what components to
look at either. Any ideas, tests, etc. I can do them. But still, this has
seemed to fix the random complete failure crashes. Or, maybe with the black
lines, has just delayed them. I can't really tell.

This seems to be caused by Chromium, BUT. I believe the colors being sent to
the screen were affecting it. Looking at my desktop, the lines were not on the
screen. They used to be in 3.14, though, even on the desktop. But, with this
glitch they were not. I opened Libreoffice, with mainly white pixels on the
left side, flipped the screen 180 degrees, and...turning off the on HDMI, or
whatever it does to the display when it flipped, fixed it, and now it's back to
normal. But, like I said, I would wager the glitch was caused by pixel colors,
or maybe colors were looked at as commands and the pixel clock frequency is a
tad off. I'm not 100% sure on any of it, just saying what fixed it for me so if
it's looked in to, it can help. If I could make a new bug report just for that,
I will.

Just had a crash while playing games, but not as bad. It was a complete loss of
responsiveness with the system, yet the mouse still rendered. I don't know if
it's an xorg problem on that or the driver, just reporting what happened. But
xorg after this update fails to render anything correctly, so now I'll be out
for testing anything until that new issue is fixed. It seems the problems that
I had before aren't fixed at all, just delayed much more with the custom kernel
with the drm patch. So the problem with random crashes and overflows, probably
isn't fixed, just delayed or better controlled with this new code. But all
other issues with the black lines, screen jumps, etc. all still exist.

Also a duplicate of the bug at
https://bugzilla.kernel.org/show_bug.cgi?id=79011. Sorry, marked it as the bug
from the forum I'm looking at, but didn't realize it encompassed multiple
bugzilla domains.
