Subject: [Known BUG?] i915 hang on 3.0.0-12 (Ubuntu 11.10 release)

Hi,

Just got below error on Ubuntu-11.10 (kernel: 3.0.0-12-generic),
and after that my screen can't show normally.
No sure if it's a known issue.

[169509.080020] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[169509.080026] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
[169509.080604] [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 1640573 at 1640569, next 1640574)
[169509.080688] [drm:i915_reset] *ERROR* Failed to reset chip.

BTW, dmesg and i915_error_state and lspci is attached.

Thanks,
Yong
