Maybe the problem isn't with IPSEC at all.  I've just had another crash on
a kernel built without IPSEC:

  panic: lockmgr: no context

Backtrace is:

This crash happened whilst I was playing with ipf (trying to get it not to
block IPv6 ICMP).  From the db> prompt, `show mbuf` gave:

  MBUF 0x13f1fa4
  trap type 0x34: cpu 0, pc=12d4060 npc=12bdf40 pstate=ffffffff991d0006<PRIV,IE>
  kernel trap 34: mem address not aligned
