Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz using the on-chip graphics. I'm using kernel-desktop-2.6.37.6-0.5.1.x86_64 & xorg-x11-driver-video-7.6-53.56.1.x86_64. The problem triggered each time I closed mutt inside an Xterm, with the Xterm located just above the notifier area of the task bar with KDE4 (not sure if this is relevant). I could still ssh into the machine, and processes seemed to still be running, but the screen no longer updated or responded (I first thought it was time to change the batteries again in the mouse & keyboard, but I now write the date on the last of the alkaline batteries and am switching to re-chargeables with a paper log of charge/install date!). I tried bringing the machine down to runlevel three and backup to five, but that didn't work. These were the only relevant messages in /var/log/messages and I notice the first time it reported twice in succession:- May 16 10:22:20 chunk kernel: [417202.246095] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU idle, missed IRQ. May 16 10:22:34 chunk kernel: [417215.750281] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU idle, missed IRQ. May 16 11:30:35 chunk kernel: [ 3333.709458] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU idle, missed IRQ. May 16 12:00:36 chunk kernel: [ 5134.409081] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU idle, missed IRQ. Nothing was recorded in X.org.log at the time (Xorg.0.log.old was last written at 11:53). I've searched around and can see various similar reports from later kernels from other distros and references to userspace triggers, but I couldn't see a conclusive reason.
