From what I understand, it is most likely a problem with grub, the physical 
location of the kernel and the default ffs version newfs uses:

dumpfs /dev/rraid0a |grep -i ffs
cylgrp  dynamic inodes  4.4BSD  sblock  FFSv2   fslevel 4

If you are using ffsv1, I don't think, from what has been said, that this is a 
problem.

When I first installed, it worked fine. Subsequent xen upgrades required me to 
decompress the kernel. Originally I was on a 500MB root partition but the 
problem still occurred which leads me to thing it's the ffs version combined 
with a relatively stale version of grub. Way back when I was looking for an 
answer myself, I seem to remember reading that grub2 was suppose to address 
this issue.
