Actually, I think the kernel is hanging in an infinite loop whilst trying to 
measure loops per jiffies...  For some reason the UP kernel isn't getting 
timer interrupts from Xen at this point, whereas the SMP kernel is.  I've not 
figured out why this could be happening, yet, but that's where I am at the 
moment.

Cheers,
Mark
