*ERROR* Hangcheck timer elapsed... GPU hung
This is happening both with MAINLINE and NEXT.
basically system is running fine, then under load system becomes really sluggish and unresponsive. I was able to get dmesg of the error..:

as for good kernels from what I remember 3.6.0-rc1. I can try a bisect on this once I get the time. or if anybody has a patch I can test.

Can you please rehand your machine, and then grab the i915_error_state from debugfs? That contains the gpu hang dump we need to diagnose things.
And the bisect would obviously be awesome.
Thanks, Daniel
