i915_error_state after the GPU hung

Hello everyone,

I am using a sandybridge-gt2+ running an amd64 3.3.0-rc2 kernel. When i tried to enable WebGL on https://maps.google.com with Firefox 10.0, my GPU hung. dmesg said:

I am attaching the i915_error_state - if you need anything else just ask here or in #intel-gfx on freenode (nick brot)

Thanks for your hard work, and keep making awesome software :)
