[Fedora-xen] Unable to reboot a domU

[Ben]

I installed a domU on x86_64 today, and was very happy. I even logged  
into it and saw that things seemed to be working, and all was well. I  
tried to reboot it, and now the domU kernel panics every time I try  
to boot. :(

The bug is 185603, and the console end with:

no fstab.sys, mounting internal defaults
Switching to new root and running init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
Kernel panic - not syncing: Attempted to kill init!

Call Trace: <ffffffff80128d62>{panic+134} <ffffffff8020b652>{__up_read

Any thoughts?
