[PATCH] i915 failed to set cursor + garbage on screen

[Przemo Firszt]

Hi,
I had some problems with 2.6.38-rc6 and xorg-driver-video-intel-2.14.0 
xorg was spitting hundreds of errors like that on the consle:

(EE) intel(0): failed to set cursor: Input/output error

and this in /var/log/kernel:

Mar  4 11:31:51 pldmachine kernel: [drm:i915_hangcheck_elapsed] *ERROR*
Hangcheck timer elapsed... GPU hung
Mar  4 11:31:51 pldmachine kernel: [drm:i915_do_wait_request] *ERROR*
i915_do_wait_request returns -11 (awaiting 1057835 at
1057827, next 1057836)
Mar  4 11:31:51 pldmachine kernel: [drm:i915_reset] *ERROR* Failed to
reset chip.

There were also mixed colours (especially in gnome-panel) and cursor was
jumping on text fields and links in iceweasel.
The attached patch found here [1] seems to solve the problem. MORE
TESTING REQUIRED as I have only one laptop with intel graphic card.

Anyone has similiar problem with PLD kernel or it's just my "custom
made" problem?
