Oh, I'LL confirm it. :o) So far it appears to me that everything to do
with this last kernel upgrade was botched from the start. I don't get
a kernel panic - just "unknown filesystem" or "can't mount filesystem"
or something along those lines. In my case Ubuntu is on an IDE drive
with a Reiser FS (although there IS a SATA drive in the machine, it's
not used with Linux at all).

I mentioned it in the thread that I started, but since you're
acknowledging this issue and have a bug filed, I'll mention it again
here. It's been my experience in the past that whenever a kernel was
upgraded via Synaptic, that the old kernel was left in place (and left
in grub's menu.lst) for this very issue - if the new kernel didn't
work, you could aways boot the old one. For some reason this upgrade
replaced my older kernel instead of just adding to the list.

So ironically I have a dead Hoary (aka stable) system that hasn't been
powered on in several days because of the new kernel, a laptop that
won't accept any version of Hoary or Breezy, but an ancient desktop
machine running an up-to-date Breezy is the only working box I have at
the moment. :o)

As an attempt to fix my main machine, I *just* booted up with the
Hoary live cd and hope to copy over an older kernel to see if that
changes anything. One question I had though - If Grub is saying that
it can't even access the filesystem on the drive, is it the kernel's
fault or Grub's? Seems to me that if the drive can't be mounted or
read, that the kernel isn't even in the equation yet. Comments?
