By "virtualization technology" you surely mean in this context VT-d (not
VT-x), correct? Anyway, seems like a GPU driver bug not willing to work
with VT-d enabled. What GPU do you have? Have you tried other kernels
(there are three shipped with Qubes R2B3)?

joanna.

Yes, I mean VT-d.
Inded, I'm quite sure about a GPU driver bug, but i'dont understand why it apprear only when I active VT-d ...
When I re-disable it, all work fine.

Graphic card is an embeded Intel Graphics Media Accelerator HD (256M)

With Linux 3.11.1-2 -> issued
With Linux 3.9.2-2 -> OK
With Linux 3.7.4-5 -> issued
