This is most curious. Based on your Xen hypervisor logs:

That are not mapped to the Dom0. Meaning that well, ..., they are not being
received by
Dom0, which definilty is a problem.

Mr Goswin,
Can you try getting the hypervisor output? That can be done by pressing Ctrl-A
three
times and one of the keys for the IRQ to domains mapping. I am just looking to
see
if you have the same issue.
</side-track>
There were some patches (cs/ 20437) that changed the IRQ mapping and I wonder if
it inadvertly triggered this failure.
Can you revert back before cs 20437 and compile Xen.gz? Here is one way I know
of how to do this (there is probably a better one):
mkdir ../test
cd ../test
hg clone ../xen-unstable.hg/ -r20436
cd xen-unstable.hg
hg tip
(and it should show c/s 20436 as the latest).
