[Maciej Rutecki]

Last known good: 2.6.33
Failing kernels: 2.6.34-rc1 and 2.6.34-rc2
Driver: Video(DRI - Intel)


When XWindow starts I got:
Mar 25 19:58:10 gumis kernel: [  133.624028] [drm:i915_hangcheck_elapsed] 
*ERROR* Hangcheck timer elapsed... GPU hung
Mar 25 19:58:10 gumis kernel: [  133.624221] render error detected, EIR: 
0x00000000
Mar 25 19:58:10 gumis kernel: [  133.624291] [drm:i915_do_wait_request] 
*ERROR* i915_do_wait_request returns -5 ( awaiting 691 at 682)
Mar 25 19:58:11 gumis kdm[2592]: X server for display :0 terminated 
unexpectedly

after this only SysRq keys work.

Similar problem (older kernels):
https://bugzilla.kernel.org/show_bug.cgi?id=15004

Workaround: setting i915.modeset=1 pci=nocrs OR i915.modeset=0

Dmesg with i915.modeset=1 pci=nocrs:
