My NetBSD/i386 2.0.2 system has stopped a few times at:

kernel: page fault trap, code=0
Stopped at    netbsd: fxp_add_rfabuf+0xce:
        jnle   netbsd: fxp_add_rfabuf+0xda
dbx

I could run "cont" and system came back alive. System clock had stopped 
while it was down, but ntpdate quickly fixed that.

I also saw:
ex0: uplistptr was 0


Here is my system:

Any ideas about this? Next time it happens, I could try a few things and 
report back.

(This is a production box.)
