Hi,
this host (used as a zfs server), was working since 8.2, actually was working
nicely under 9.1, but after upgrading to the latest 9.2, it panics, 2 days
in a row. Appart of being a newer version, it's now dataless while I run it
through the loops - which could be the reason for the panics, so while I
prepare
it to run off a local disk, and see if that mitigates the problem,
could someone take a look?
