Looks like it is due to Kevin Wolf's changeset 17499. Your attempt to go
back to older tools obviously didn't work -- the backtrace in xend.log comes
from a line introduced by c/s 17499.

Well, the obvious answer is to print less drivel in the VT-d code. There's
no reason at all to print so much useless text, even in a debug build.

Actually a second point is that we should drop characters from the 16kB
serial buffer rather than spin in the hypervisor waiting for the buffer to
empty. I'll implement that.
