Hi,
I've posted this earlier but didn't see it appear on the list, so i
subscribed to the list, and now post it again.

I own an Asus P7P55D-EVO board, which has vtx and vt-d features enabled in
the BIOS (i'm running the latest firmware 1207), however for me this
platform won't boot with iommu enabled.
Here I've included a failing boot log (iommu=1), and a lspci output for a
working boot (with iommu=0).
Let me know if there's other info you would like to see of this system.
I'd love to run this with the tuner cards in one hvm, and the graphics
card in another hvm...

Recent xen (from xen-unstable) shows the following when i boot:
