That's strange, given it obviously is capable of rebooting into dom0, given 
your previous errors not finding root.

I think your initrd line may be wrong, by the way - you're specifying a xenU 
initrd, not a xen0 initrd.  Did you mean to do this?

I'm afraid I'm not so familiar with the start of day code, so I'm not sure 
what's going on...  but it does look like it really ought to be possible to 
get things working better!

Cheers,
Mark
