Bug 590265

Description of problem:

On my i5-520m (Arrandale) integrated graphics (Thinkpad T410s) the 2D graphics works fine, but when I turn on desktop-effects/compiz then X freezes after a short while. I can still SSH into the laptop, but I cannot kill X.


Version-Release number of selected component (if applicable):

kernel-2.6.33.3-85.fc13.x86_64
xorg-x11-server-Xorg-1.8.0-12.fc13.x86_64
xorg-x11-drv-intel-2.11.0-4.fc13.x86_64
mesa-libGL-7.8.1-6.fc13.x86_64
mesa-dri-drivers-7.8.1-6.fc13.x86_64
mesa-libGLU-7.8.1-6.fc13.x86_64

How reproducible:

Freeze is not immediate, but happens always.

Steps to Reproduce:
1. Enable desktop-effects.
2. Keep using the system for about 1 minute
3. X freezes
