Originally I had an 8.1 server setup on a 32bit kernel. The OS is on a
UFS filesystem and (it's a mail server) the business part of the
operation is on ZFS.
One day it crashed with an odd kernel panic. I assumed it was a memory
issue so I had more RAM installed. I tried to get a PAE kernel working
to use this extra ram but it was crashing every few hours.
Suspecting a hardware issue all the hardware was replaced.
I had some difficulty trying to figure out how to mount my old ZFS
partition but eventually did so.
zpool import shows this:
pool: email
id: 10433152746165646153
state: ONLINE
status: The pool was last accessed by another system.
action: The pool can be imported using its name or numeric identifier and
the '-f' flag.

zpool import -f -R /altroot 10433152746165646153 olddata
panics the kernel. Similar panic as seen in all the other kernel versions.

Shows a typical kernel panic.

Gives a bit more info about things I've tried. Whatever it is seems to
affect a wide variety of kernels.
Any ideas?
