Description Oswald Buddenhagen 2009-12-06 09:29:52 UTC
Dec  6 17:18:15 err [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
Dec  6 17:18:15 err render error detected, EIR: 0x00000000
Dec  6 17:18:15 warning i915: Waking up sleeping processes
Dec  6 17:18:15 warning reboot required

so far, so good. kinda.
but then i get these to no end:

Dec  6 17:18:16 err [drm:i915_gem_execbuffer] *ERROR* Execbuf while wedged

obviously, this isn't a particularly good idea. the error condition should be propagated upwards and acted upon (i.e., no further requests made, server shutdown). one could also implement a simple flood protection, but that seems wrong.

Eric has applied the patch, so it will be in the next kernel. Thanks.
