Hi,
I am seeing an occasional kernel panic. I think it
is related to natd and ip_divert

This lock order reversal is not a problem. See
http://www.geocrawler.com/lists/3/FreeBSD/147/50/6267627/
for the meta-issue of witness being too verbose; I'd post URL's for
the followup discussion but there wasn't any.

This is on relatively old (~ three months) sources. The first lock is
from swapout_procs(); I assume the second lock actually refers to the
call to

Hi,
with -current sources (as of -now) I get during startup:
lock order reversal
1st vnode interlock last acquired @ ../../kern/vfs_vnops.c:625
2nd 0xc0306840 mntvnode @ ../../ufs/ffs/ffs_vfsops.c:940

Is that bad?

In noticed this lock order reversal while shutting down the system to
single-user in order to make installworld of my cvsup of today. I then
tried again with the new world and the l.o.r. was still there.

Hi,
these represent machine lockups, if not false positives.
