You need to give a bit more information if you can. This is a kernel you've
built (root@foo.acn.pl:/usr/src/sys/compile/KROWA). Use nm to tell us what
corresponds to the pc and ra values in the trap message. Better yet, build
with

	options DDB

and when it panics, type

	t<RET>

to get a stack trace.

Can you still reproduce this with newer releases?
