[BUG] GPU hung

Hi,

I found a problem with the i915 driver. That is when I use x-window, the window will die soon later, and I get the following message:

[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 24198 at 24196)

But there is no problem if I change to tty2 when x-window die.

The following is the environment of my box: OS: Fedora13 Kernel: the latest code in the tip tree VGA controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller

The attached file is the config of the kernel.

Thanks Miao
