Recently I lost power (along with much of New England) for eight days.
When the juice started flowing again, I restarted my Xen server (Debian
Squeeze, dual Xeon (8 cores), 16GB RAM), which came up fine but had a
pile of package updates pending...

===============================================================================
I did an "aptitude safe-upgrade" without even really looking at it. At
the time, I had an HVM domU running. The upgrade crashed the system.
I'm pretty sure it crashed while configuring the
xen-hypervisor-4.0-amd64 package. When I brought it back up, I ran a
"dpkg --configure -a" to finish the job.
However, now, when I try to use my Windows HVM, I always get a kernel
panic dealing with the vbd. For example...

========8<=================
Then the system destabilizes.
I have a pretty common setup. I can't be the only one!
What the heck happened with those updates?!? Please help me out!
thanks,
