I think the BIOS is broken with respect to VT-d. Please try to update to the
latest BIOS.
Thanks,

Subject: [Xen-devel] VT-d on Asus P7P55D-Evo: IOMMU not supported
Hi,
Having updated my Xen to 4.0-rc9-pre recently, i decided to try
booting without the iommu=0 flag.
The system doesn't crash now (which is an improvement), but gracefully
disables VT-d due to an
unsupported IOMMU.
I've attached the output of xm dmesg, hope it is of use to someone.
Do let me know if there's something more i can do to help in getting
VT-d working on this board.
Regards,
Mark.
