netbsd-5 locking panic


on a pf based router upgraded to NetBSD 5.0_RC4 built from Friday's
sources, I saw the following crash (ahh, conserver...):

login:  [-- hf@localhost detached -- Fri Apr 24 19:08:22 2009]
Mutex error: mutex_vector_enter: locking against myself

lock address : 0x00000000ca204f80
current cpu  :                  0
current lwp  : 0x00000000ca207a00
owner field  : 0x00000000ca207a00 wait/spin:                0/0

panic: lock error
Begin traceback...
at 0xca204f80
Bad frame pointer: 0xc03d1a33
End traceback...

The kernel was built without debug options. There is no core dump, and
pflog left behind a file "pflog.bad.7e9c5e91", which has

until EOF.

Does that speak to anyone?
