Not really.

It seems to happen at random, usually shortly after boot and as I
mentioned, there is some indications of it being related to munged

Amongst these indications:

Booting single-user and running fsck (without -p) almost always
prevents it from happening until after next crash, and I think all
the backtraces I've see have been UFS or maybe even WITNESS+UFS

If it is WITNESS related, the serial console is obviously a
prime suspect...

But all that said, I havn't seen it for a couple of days...
