I got the panic once again. This time I had ddb.onpanic=1. I got
backtrace from ddb -- it was almost the same backtrace which was
reported by Martti Kuparinen at the beginning of this thread. This
is on NetBSD 4.0_STABLE, so the problem doesn't touch only netbsd-3.
I think it's really worth fixing.
Sorry not posting backtrace, but dmesg on the core file showed nothing
and gdb shows nothing useful, too.
I hope you guys will fix it, so we have working NetBSD + ipf + ipv6
