[Xen-users] domU freezes solid after startup -- why?

Thanks.

When I did the above, I discovered that the console output had frozen
at a particular point.  Nothing more happened after that.

I went and did other things for about FOUR HOURS, and when I returned
and looked at the console output, there was still no further output.

See the attached file.  The last two lines of console output happened
after I did an "xm shutdown" on the domU.

Any ideas as to why my domU is hanging like this?  What sorts of
diagnostic measures should I try next?
