This is Debian bug 619781, filed here at Ben Hutchings' request. Sometimes, starting mplayer video playback on this machine causes the screen to blank. Lots of kernel messages appear: Mar 26 16:02:49 twilight kernel: [ 1552.973035] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung Mar 26 16:02:49 twilight kernel: [ 1552.973881] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -11 (awaiting 302417 at 302416, next 302439) Mar 26 16:02:49 twilight kernel: [ 1552.974222] [drm:init_ring_common] *ERROR* render ring initialization failed ctl 00000000 head 00000000 tail 00000000 start 00000000 Mar 26 16:02:49 twilight kernel: [ 1553.292337] [drm:i915_do_wait_request] *ERROR* something (likely vbetool) disabled interrupts, re-enabling ...

After this happens, the machine is still running and reachable via ssh. This is on a Thinkpad T61 with a "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller", according to lspci. The kernel is Linux version 2.6.38-1-amd64 (Debian 2.6.38-1) (ben@decadent.org.uk) (gcc version 4.4.5 (Debian 4.4.5-14) ) #1 SMP Wed Mar 16 17:38:02 UTC 2011
On the Debian bug, Cyril Brulebois noted: -------------------------------------------------------------------- Hi, Yan Li <yanli@gnome.org> (07/04/2011): > Upstream has provided with a fix to xf86-video-intel, please help to > test and integrate. > > commit 23f9b14df7c102c1036134835dd5d1a508059858 > Author: Chris Wilson <chris@chris-wilson.co.uk> > Date: Sat Feb 12 10:42:34 2011 +0000 that's included in the 2:2.14.902-1+exp1 package in experimental. You'll need to upgrade your X server as well. Or wait a few days until the X stack migrates to testing, and 2:2.14.902-1 will be uploaded to unstable at that point. KiBi.
Hi, this seems to be fixed now, perhaps due to the fix in bug 34017: https://bugs.freedesktop.org/show_bug.cgi?id=34017
