Date: Sun, 17 Dec 2000 17:05:44 -0800 From: Doug Barton <DougB@gorean.org> To: freebsd-current@freebsd.org Subject: Panic with fairly up to date -current, seems NFS related Message-ID: <3A3D62E8.4453C765@gorean.org>
next in thread | raw e-mail | index | archive | help
I built -current world and kernel around 3am PST sunday morning with up
to date sources. Later that same day I added Poul-Henning's console
logging patch. Just a few minutes ago I had a lockup and panic that
thankfully produced a kernel core to work with. It looks like this is
not related to phk's patch, but rather to an NFS issue that I've seen
before. I was copying a 23M file over NFS (mounted via amd) when this
lockup and panic happened.
My workstation is the NFS client, running -current. The NFS server is
running FreeBSD 3.5.1-STABLE-1014 #0: Mon Oct 16 00:00:13 PDT 2000. If
anyone wants me to do more debugging with this, let me know. I'm going
out in a bit, but I will likely be available later tonight or tomorrow.

Here are the results from a previous similar experience on 11/29 that I
neglected to pass on. They are eerily similar, which is why I really
don't think phk's patch is involved.
