I've attached the output of a boot -v at the end of this message.

On this box the problem was pretty easy to reproduce. It occured nearly
every cvsup. It doesn't happen at the beginning, only it has been running
for a while. Never saw it on another box.
As far a I know the box doesn't suffer from other panics. I always saw
something with ffs_*. Always under the same conditions (running cvsup).
Since the box is/can do SMP, I try to grab source as soon as possible and
rebuild with SMP enabled, but won't get very far since the panics.

I hope this will help get you far enough. If not, just ask/shout :)
