Thanks for the information Adrian.  Just to be clear, are you still
running xen-3.0.2-3.FC5 with the latest kernel-xen0-2.6.17-1.2157_FC5 on
the dom0's, but have rolled back just the domU kernels?  Since my
xen-3.0.1-4 dom0's and U's have been running for months now I think I'll
just stick with this version for the time being.

Adding the following line to your domU config makes it easy to get the
panic messages:

on_crash    = 'preserve'

Regards,

Matt.
