Panic in netnatm

Hi,

I did a cvsup, rebuilt everything ( buildworld, buildkernel, installkernel,
mergemaster -p, installworld) and now I get a panic very early when
my fatm card initializes:

panic: mutex natm_mtx not owned at /usr/src/sys/netnatm/natm_pcb.c:110

I have a dump file, but kgdb cannot read it:
kgdb: kvm_read: invalid address (0x4)

I'll try to get a more useful trace tonight.
