i915: Detected a hung GPU, disabling acceleration

[Olivier Cochard-Labbé]

Hi,

On my new HP laptop with FreeBSD 9.1-Release (amd64) I've got this
message after few hours of xorg usage:
(EE) intel(0): Detected a hung GPU, disabling acceleration.

This produce color problem on my open windows, but if I close all of
them and re-open them, the problem disappear.
Then I've followed the wiki advice regarding Intel GPU and put here the logs:

* i915.dmesg.log
* i915.pciconf.txt :pciconf -lvb
* i915.xorg.log
* hw.dri.0.info.i915_error_state

Regards,

Olivier
