I am seeing a lot of other trouble with IPSEC implementation at the
moment. Multiple 0xdeadc0de accesses and I have successfully been able
to panic my router test box by at least 3 different ways.

Last sunday evening I have been able to prevent this by some patch
(unusable in any productive setup).

I am currently trying to narrow the problem down and cleanup all my
debugging from kernel but had no time last evenings. Hopefully I will
find the time on weekend.

In the meantime there are two things you can do:

a) if you do not need IPv6 you may use FAST_IPSEC which worked for me
b) re-enable all debugging and perhaps let me know if you can see
   messages like:
	Invalid policy for PCB -559038242	(0xdeadc0de)
   or crashes/panic reated to ipsec.
   Any backtrace will of course not show the real problem but give
   some idea when the access to 0xdeadc0de happens (I have seen three
   possible paths here).
