            Bug ID: 113341
           Summary: GPU Lockup on AMD Kaveri
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.4.2
          Hardware: x86-64
                OS: Linux

            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: linux@bernd-steinhauser.de
        Regression: No

journal log from the time of the gpu lockup.

GPU is an AMD Kaveri: 1002:130f
Happened when I started an application (way before the application actually
showen) on KDE Plasma 5.5.
The kernel version was 4.4.2 with an additional vblank fix applied (see [1]). 

Since I wasn't prepared for this and ssh wasn't activated and I couldn't save
dmesg output. Instead I'll attach what I found in the journal.

I forgot about Xorg log, sorry. Since only one old one is kept, it's gone
already.
Maybe logging to syslog/journal is a good idea ...

Today I ran into this again and got the Xorg log, but there doesn't seem to be
anything interesting in it.
Kernel is now 4.4.4.

When the freeze occurs, I can still ssh into the system. Applications continue
to run (i.e. I had a music player running), I could even reboot the system,
although that seemed to take longer because X didn't like to shutdown (was
markt as DSsl+ in ps aux).

Any chance you could try if this also happens with LLVM 3.8 or even current
SVN/Git?

Does it always happen when starting a particular application?

I tried to build LLVM/clang scm, but it failed (have to check why and if I can
get around that).

I've had several freezes over the last few weeks (most of them when I bisected
that other bug mentioned above (so could be unrelated), but only a few after
staying on 4.4.x), but this one was the only one I could relate to a specific
event, starting an application (thunderbird here).
The other ones seemed to happen out of nowhere, so it could be that it was just
coincidence that it happened when I started that application.

FWIW, right now it's better to try LLVM 3.8 than SVN/Git, because the latter
will expose you to https://bugs.freedesktop.org/show_bug.cgi?id=94242 .

I will try to build llvm, but it could require me a few days since it's not yet
provided by my distribution and I have to check the changes in the build
system.

BTW, I can usually ssh into the system. Is there any way I could gather more
debug info when this happens?

--- Comment #10 from Bernd Steinhauser <linux@bernd-steinhauser.de> ---
During the last 2 weeks I switched between amdgpu and radeon a couple of times.
What I noticed is that with radeon I do get lockups here and there, I think
almost always (not 100% sure though) when a video is running.
Both with xv and vdpau as video output.
llvm is now 3.8.

On amdgpu I haven't seen a lockup yet, except for a view when bisecting 4.4-rc2
or -rc3, but I guess that was a different problem which got fixed until the
release.

--- Comment #11 from Bernd Steinhauser <linux@bernd-steinhauser.de> ---
Since I'm now exclusively using amdgpu and since that works very well for me, I
didn't do much more tests with radeon and thus cannot tell if this is still
present or not.
Therefore closing the bug report.
