>Description:
My NetBSD/i386 2.0.2 system has stopped maybe eight times over
past few weeks at:

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

(Hope I copied that correct.)

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" but probably not related.)
