wm0 panic

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

Trying a today's -current/amd64 with DIAGNOSTIC/DEBUG/LOCKDEBUG, I can
boot multiuser without a network. If I log in as root, as soon as I hit
enter:

(box is happily usable without the LOCKDEBUG - it just means I can't debug
what I'm trying to get at...)
(must try with biosboot instead fo EFI which is the case here)
