[bisected] i915: linux-2.6.32-rc3+ regression

Hi!

After syncing git tree to bd381934bf13ccb1af2813ae26c6fe00ec85d254
I've experienced pixel color corruption in Xorg.
Some of pixels (not all) have abnormal colors seen on images like this:
http://trofimeus.narod.ru/2009-10-09-22-00-17.png [1.5M]
(you won't see any problem until you run -rc3+ kernel).

I've bisected it[2] and found offending commit[1].
My hardware is HP Compaq 2510p laptop:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

Do you need more info?

Thanks!

I found that today too.
I had filled a bugreport.
https://bugs.freedesktop.org/show_bug.cgi?id=24444


Same commit is responsible.

Would you please notify me about _kernel_ regression reports filed at

Are you running X.org server 1.7 + driver? if so there is a bug in the current
released driver between that combination, the fix is on the intel-gfx
mailing list.

The 1.6 X server + same driver doesn't show this problem.

Yes, both driver and xorg-server are current -git masters.
