Sigh, this is becoming quite annoying.

panic: kkernel: page fault trap, code=0

That's exact wording, there was a slight typo in my last email (movl).
kkernel is kkernel, not a typo.

Still unsure how to debug it so all I can do is say I haven't changed my
config recently.

It's NetBSD 1.5 i386 Generic running on a pentium 100. Using rasppoe for a
dsl connection and ipfilters/ipnat (forwarding = 1) to provide a gateway for
lan net access.

The system previously ran NT4 server for about 2-3 years without hicups
(usually 7-10 day uptimes before being shut down on purpose or
powerfailures).

Also I just tried to reboot it and got this:

swapctl: adding /dev/wd0b as swap device at priority 0
Automatic boot in progress: starting file system checks./dev/rwd0a: 3634
files, 27625 used, 56859 free (1155 frags, 6963 blocks, 1.4% fragmentation)
/dev/rwd0a: MARKING FILE SYSTEM CLEAN

Thanks,
