Does "snapacct_ufs2: bad block" really mean "bad" as in "unreadable"?
RTFS I tought it was just a "logic" inconsistency.

Anyway, after having de-activated all snapshots for weeks (and deleted
all the old ones) I got this panic again.

I'm currently doing a "dd if=/dev/ad0 of=/dev/null bs=1m" as suggested
by dd(1) in order to be sure it is not an hardwareissue.

And if all is well I will "dd if=/dev/ad0 of=/dev/ad0 bs=1m" too.

And then recompile with latest -STABLE just to be sure to have the
latest amd64-based snapshot fixes.

Hope this is the last time I see that panic... -_-
