Description Slava Gorbunov 2011-11-01 08:50:35 UTC 
On Sandy Bridge integrated GPU, active usage of it (OpenGL applications or even playing video through XV) hangs GPU (mesage "Hangcheck timer elapsed... GPU hung" is logged to dmesg, and accelleration is turned off by X server). Sometimes it freezes the whole system.

This patch: http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=786a770f528a0daee2971494352672cb89f48384
appears to fix this issue. At least I don't observe GPU hanging for more than 24 hours after rebuilding xf86-video-intel with this patch applied (without it, the problem usually appears in several hours). Please include it into ebuild.

Reproducible: Always

Should be fixed in 2.16.901 already, can you test that?

I have this issue with xf86-video-intel-2.17.0-r2 (dri sna) too. See URL for more information about this bug on freedesktop.org.

Does the patch from bug 393427 help? (Upstream bug report https://bugs.freedesktop.org/show_bug.cgi?id=43552 )
Comment 4 bugzilla93443 2011-12-07 18:58:32 UTC 
Same problem with patch:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm] capturing error event; look for more information in /debug/dri/0/i915_error_state

I have opened a new bugreport at freedesktop.org with my i915_error_state because there are so many different types of bugs after this abstract message.

Ok, I will close this bug now as yours is a different issue than the original report.
