That looks exactly like the problem I reported about 2 month ago under
the topic "What's the magic to compile a unified dom0 and domU kernel
image?". Very nice to see that I'm not the only one with problems like
this. I think there MUST be some type of bug in the XEN 2.0.7 (?) code.

I just tried with my failing kernel config: When disabling
CONFIG_XEN_PHYSDEV_ACCESS the domU comes up, otherwise not.

Greetings,
Markus
