Uh, yeah...

Xen has many, many problems with interrupt handling and is utterly
unsuitable for running anything that depends on hardware peripherals. I
speak from very painful experience.

There is no way, under any circumstance, that I would try to run
Asterisk with interface cards in a Xen environment. It's too bad you
wasted so much time trying to fix it -- it's never going to work.

Try ripping Xen out and doing it directly on the physical server. I
think you'll find your problems will go away.
