Description of problem:
after enabling VT-d in BIOS of my ThinkPad T510, my logs get flooded by error messages, leading to performance problems and my harddisk filing up (over 400 GB in just a few hours)

Version-Release number of selected component (if applicable):
kernel-2.6.34.6-54.fc13.x86_64

How reproducible:
always

Steps to Reproduce:
1. enable VT-d in BIOS
2. boot
3. tail /var/log/messages

I really do not know what is behind those messages, I don't use this component, don't know if it works or not
