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. 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. In fact, on the
T510, I couldn't even get an installation to complete without turning
it off.
