Kernel Bug Tracker – Bug 32102
Spurious GPU hangups with 2.6.38
Last modified: 2011-03-29 08:13:22 UTC
From time to time the screen in X freezes for a couple of seconds, then X gets killed. In dmesg I see the following:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 533849 at 533847, next 533850)
[drm:i915_reset] *ERROR* Failed to reset chip.
Attempting to restart X results in blank display and completely hung X (does not even respond to Ctrl+Alt+Fn); the only way out is SysRq.
I've seen a similar bug 31102, but in my case there is no Chromium, only minimalistic KDE setup. So I believe this bug has different origin.
My HW configuration is the same as in bug 27322. I am using xf86-video-intel-2.14.0.
Forgot to add that I experienced no such hangups when running 2.6.37.
Not, it's the same bug as 31102.
