Why it's so short? Can post complete output?

And also that is a panic. Why it's not consistent with the sighting described 
in your previous mails?

I suspect your environment is not incorrect in somewhere. Pls list the 
following info: platform, BIOS, dom0 changeset, Xen changeset, did you add-on 
extra graphics card? did you follow steps listed in docs/misc/vtd.txt?

Actually, latest Xen VT-d is quite stable in our recent testing.
