Description of problem:
After having installed new Kernel version 2.6.35.13-91.fc14.x86_64 system freezes partially at start-up, runtime and shutting down.

Version-Release number of selected component (if applicable):
Linux localhost.localdomain 2.6.35.13-91.fc14.x86_64 #1 SMP Tue May 3 13:23:06 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux


How reproducible:
Use Kernel 2.6.35.13-91.fc14.x86_64. Observe system freezing. Then move mouse or touch-pad and system will carry on. When that does not work hit shut off button and cancel shut-down dialogue. Using previous Kernel version renders normal system performance.

2.Observe system freezing
3.Use previous Kernel version which renders normal system performance
