Yes, that's a possible culprit. I've had massive problems with VT-d
enabled on both a Thinkpad T510 and on a Thinkpad X220.
the strange is that both machines are running since
august 2011 until around F16 with stable graphics
and VT-d
so there must gone something wrong in the latest kernels
I don't pretend to understand what advantages VT-d is *supposed*
to give me, but it's the first thing I turn off in the BIOS
on a normal workstation VT-x and VT-d can and should be turned off
here are running some VMware Workstation guests in background
one of them is a backup-machine rsync'ing 1.5 TB data
each day - in this case you do not want to disable VT-d
