OK. Got another one and here's the traceback:

_Debugger
_panic
_lockmgr
_ufs_lock
_vn_lock
_vrele
_nfs_lookup
_namei
_vn_open
_sys_open
_syscall
_trap

If this is similar to the ones Frederick has been seeing than it looks 
like it's NFS related. Both of us are building packages from NFS mounted 
volumes when the panic happens.
