Bug 26229

Forwarding a bug from Ubuntu user lykwydchykyn:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/510830

[Problem]
Display freezes during the KDE login process. GPU hung and batchbuffer dump attached.Bug was originally reported for Ubuntu Lucid which has kernel 2.6.32 and intel driver 2.9.1, but the bachbuffer dump and log here are from kernel 2.6.33-rc5 and new git-snapshots of xorg from xorg-edgers.

[Original report]
Using Ubuntu Lucid (10.04) with latest updates 1/20/10. Graphics chip is intel 845G in a Dell GX60.
In KDE, enabling compositing under System Settings causes X to freeze up. System does not respond to anything except alt+sysrq commands.

After reboot, X freezes during user login, presumably when Kwin is being started but that's just a guess (it locks about 3/4 of the way
through the login splash animation).
