Attaching /sys/class/drm/card0/error as directed in the dmesg. Could this be caused by a recent switch to SNA?

I have switched to UXA for now, and that seems to have solved all the problems: I don't see any display glitches, and no lock-ups. The "stuck on render ring" messages are also gone.

Let me know if I can provide any more debugging information.

I've been seeing the same glitches, starting when the updated mesa packages were pushed out on 2/20: http://ubuntuforums.org/showthread.php?t=2206883

At exactly the same time the glitches appeared, the primus bridge quit working for Bumblebee: https://github.com/amonakov/primus/issues/133

Backleveling mesa to the packages in the saucy repository causes the graphical glitches to disappear and everything looks normal again.

Another i915 user running KDE here: I started experiencing the exact problems after the package pushes on 2/20.

The screen corruption doesn't always start immediately, but when it does it's horrible: http://i.imgur.com/W2N2y6e.png

Hangups/crashes are frequent (multiple times a day).

I backleveled the mesa (to saucy packages) and xserver-xorg-video-intel (to xserver-xorg-video-intel_2.99.910+git20140210) , and the corruption/crashes went away.

The current packages also break Primus (the render window is solid black). Backleveling the mesa/intel packages fixes this issue as well.

It's a mesa thing, it's me being confused since the bugzilla update somehow ended up in my kernel bugs folder.

For bisecting mesa you can simply build from sources without any need to install anything. You only need to set LIBGL_DRIVERS_PATH to the i965_dri.so binary built by mesa, e.g.

LIBGL_DRIVERS_PATH=~/home/mesa/src/mesa/drivers/dri/i965/.libs/ glxinfo

Mesa built from git has the git version tag in the Gl version string embedded, so you can check you run the right thing.

Following the instructions to build mesa, I think I was able to get it running successfully:

rdhruva@ubuntu:~/build/mesa$ LIBGL_DRIVERS_PATH=./lib LD_PRELOAD=./lib/libGL.so.1 glxinfo | grep -i version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.2.0-devel (git-079bff5)
OpenGL core profile shading language version string: 3.30
OpenGL version string: 3.0 Mesa 10.2.0-devel (git-079bff5)
OpenGL shading language version string: 1.30

Now when I try "glxgears", everything is fine. I am unable to determine if this because the latest git checkout fixed the problem, or if the problem is not surfacing because I am running X in the UXA acceleration mode (instead of SNA).

Looking at the logs, can you suggest a good way to reproduce this problem? Thanks!

You need to check out the same version of mesa you have currently installed, to make sure you can reproduce the issue correctly when building from sources. Then the same for the last known working version.

Only once that's confirmed should you start the bisect.

Hello: what can I provide to remove the NEEDINFO status? I am confused whether the git bisect is still required: Chris' message seems to imply that the problem might be completely visible in the attached error file.

If a bisect is indeed required, I am not sure if it's for i965 or i915 (the dmesg errors reference i915).

Chris comment was just about your statement in comment #17 that this is i915 related: The kernel driver is called i915, but the mesa driver for your hw is i965. And like Chris said the kernel is just the messenger.

In short, the bisect of mesa is still required, nothing changed.

Daniel: I updated my git repo and checked out version 10.1 (which is what my install currently hast). I am still unable to repro the problem from git checkout because the moment I start X with "AccelMethod uxa", the problem goes away.

Is there any better of testing this one library against an X which is not started with UXA? Starting X with SNA and testing this is not really an option because everything is unusable then.

GPU crash dump in /sys/class/drm/card0/error Edit (2.9 MiB, text/plain)

Sorry for re-opening this bug, but I think it is not fixed yet. (or Ubuntu`s xserver-xorg-video-intel is latest in upsream. I heared that 2.99.912 is released in June 10th.)

Maybe this will help for debuging. (I got gliches 3~4 times per day.)

Do I need to test lastest one by using xorg-edgers ppa ?

#40

I am experiencing the same problem on a Dell Inspiron 6400 with an Intel GM945 display controller. Symptoms occur frequently when using chromium-browser. Forcing AccelMethod to "UXA" resolved the symptoms. I'm using Ubuntu 14.04, kernel 3.13.0-32-generic, and xserver-xorg-video-intel version 2:2.99.910-0ubuntu1.

Hey guys, is there any chance to fix this crap in up to date 14.04? My system hangs suddenly every day...

I have reported this to the freedesktop.org, and it seems that Chris Wilson, one of the moderator of the open-source Intel graphic driver, is been watching my bug report.

crash dump Edit (3.2 MiB, text/plain)

I face the same issue on a fresh installed ubuntu 14.10 with a celeron haswell processor, especially when browsing with firefox it sometimes happens.

for what it worth,

I was having the same issues using kernel 3.18.2-031802-generic (amd64) from http://kernel.ubuntu.com/~kernel-ppa/mainline/

I've updated to kernel 3.19.8-031908-generic (amd64) and I no longer get "ERROR* gpu hanging too fast, banning" or [drm] GPU HANG...

looks like the original bug reporter doesn't have this bug anymore, as the upstream bug is closed, and the kernel is also a newer one in wily

if you still see hangs in wily, file a new bug.
