I''m trying Xen 4 on newer hardware than my previous attempt and
running into a slightly different issue. This is on 2.6.32.15-stable,
but I have tried Xen 4.0.0 against 2.6.32.13-stable as well with the
same results. This looks more like a Xen bug to me, based on the stack
overrun.
The dom0 kernel is booting natively without any issues.
