GPU hung (not reproducible) Today I got this while starting a video in SMplayer (MPlayer) with 2.6.38-rc6-00113-g4662db4: [ 830.880014] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

[ 839.040367] [drm:i915_reset] *ERROR* Failed to reset chip. Screen was almost freezed, cursor was stuck but the machine was alive and I was able to use SysRq to kill X and try to restart it (but that didn't help). I don't remember anything similar in recent kernels (<= 2.6.37) and got this only once with 2.6.38-rcX. Environment at the time of the GPU crash: KDE4 (without "Desktop Effects") Chromium Claws Mail Dolphin ccached make -j3 on a just pulled linux-tree (so I/O bound) SMPlayer/Mplayer (just launched) Assorted logs attached.
