Description of problem:

kernel oops after graphical login

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

Linux lenovo.badmuts.org 2.6.31.6-145.fc12.x86_64 #1 SMP Sat Nov 21 15:57:45 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
xorg-x11-drv-intel-2.9.1-1.fc12.x86_64

How reproducible:

Every other time or so

Steps to Reproduce:
1. boot
2. login
3. system hangs before desktop is being displayed
  
Actual results:

System hangs

Expected results:

Normal startup

Additional info:

System is Lenovo thinkpad SL500 with Intel graphics. Hangs a few seconds after login, while starting X/KDE. I have to reboot, and mostly on a second boot, it works. Can it be that it crashes only on cold start or when Windows 7 has run before?
