You really think its more likely to be a dom0 issue than a Xen issue?
I might have to revert to 3.4 if I can't get this working soon. I'm
going to play around with it a little more today but I double checked
the wiki and it doesn't seem I missed anything. I will try your
suggestion and see if it helps, but other than that the only thing I
can think of is maybe forward to xen-devel? Maybe they can spot
something thats not right.
