[Bug 946899] Re: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

[peterbo]

schymans: I am running 13.04 so have not tested on 12.10. The crash you
describe sounds a bit worse than the gpu hang but I obviously cannot be
sure. My laptop never rebooted when the hang occurred though.

I must admit that I had one hang with rc5 after 7 days, however the
error message was different than the usual "Hangcheck timer elapsed". It
was something with a "ring" - cannot remember any more of it. It
happened after having dual monitors connected, suspending my laptop and
then opening it without any monitors connected. Am on rc6 now and no
problems yet.

I cannot seem to force the hang, neither by running glxspheres, dragging
windows fast across the desktop or playing with compiz effetcs/settings.
