Subject: Re: Another serious bug in NetBSD-1.6.1

Hello David et al. I want to appologize in advance for the seemingly
i386 slant on this particular message. I'm preparing for an international
trip, and I wanted to get this out to the group before I left. Thus, it's
not quite as clean as I'd like. Below is the disassembled listing of the
genfs_putpages function in I386 form. David asked which section of the
code was executing when the trap was called, and I hope this answers that
question. (I would have found the particular lines in C if I had had more
time.)
In any case, I'm running:
/* $NetBSD: genfs_vnops.c,v 1.63.2.2 2002/10/23 12:18:12 lukem Exp $
The listing of the assembly from the particular panicing kernel in question
is below. Perhaps this will shed light on the problem.
