This is the point where you would normally start to see dom0 output.

Have you enabled the XEN HVC driver in your kernel and passed
console=hvc0 to the kernel?

If you have then you could trying pressing CTRL-A three times to enable
Xen debug keys, then try various keys to see if you can see if/where
dom0 has crashed ('h' lists them, 'q' is a good one, there is also one
to dump the dom0 state).

After that I think it would be a case of adding calls to xen_raw_printk
in the kernel and building a hypervisor with debuging enabled to get
some kernel output -- which will hopefully show where things go wrong.

Ian.
