Sorry for late reply however I was very busy.
I attempted to replicate your problem on xen-unstable (C/S
21035:257589edefb3) and linux-2.6.18-xen.hg (C/S 1005:f7f420bd7b7a)
on IBM x3650 (7979 4AG). I do not have seen any strange behavior.
I have also done some Dom0 stress testing (linux kernel compiling
with make -j 17 through two days). Currently it is still working
without any problem.

Did you tested your setup on another machine ???

I could not do more without access to similar machine.

If you have any questions please drop me a line.

Daniel
