I think my problem is related to routing code too.

(kgdb) l *0xc0585ee5
0xc0585ee5 is in _mtx_lock_sleep (/usr/src/sys/kern/kern_mutex.c:363).

$1 = {lock_object = {lo_name = 0xc0807e84 "rtentry", lo_type = 0xc0807e84 "rtentry", lo_flags = 21102592, lo_witness_data = {lod_list = {
        stqe_next = 0x0}, lod_witness = 0x0}}, mtx_lock = 6, mtx_recurse = 0}


The mtx_lock value is 6 - this is MTX_DESTROYED.
