Hi all,

The system came up again with no problem, but paniced again as soon as it
loaded linux.ko from /etc/rc. Here it mentioned something about mtx_* but,
assuming this could be reproduced, I was so stupid that I didn't write it
down...
Took this out, rebooted and then tried kldload linux.ko and no panic :(
Right now it looks like this won't be easy to reproduce... I will try to boot
again and again until I get a new panic.
Anything I should do, apart from dumbly rebooting until I get it again? I have
INVARIANTS_SUPPORT and INVARIANTS compiled in, but no DDB, WITNESS or
MUTEX_DEBUG anymore... Should I put those back?
Bye,
Andrea
