[Xen-devel] Fatal page fault on xen-unstable tip (vt-d related maybe?)

I just updated to a more recent unstable (17826) and got this
fatal page fault on boot.  I backed off to 17772 (which I'm told
was good on another machine) and got the same.  I suspect it
is something peculiar to my hardware -- an Intel "Weybridge"
box -- which I think has VT-d support though I am not currently
using it.

I can't binary search the exact cset right now, but thought
I'd report it.
