Subject:   CURRENT crash (NFS-related on a system not using NFS???)

This is the second time I've seen this crash on CURRENT in the last 3-4
days. After it happened the first time I disabled ACPI, but that does =
not
seem to make any difference. This one happened on a system compiled from
sources dated 2004.09.20.20.00.00. I'm not a kernel hacker, but the
references to NFS seems strange given that I'm not using NFS on this
machine. I do have a core dump saved in case someone wants further
information.

NFS is compiled into the kernel (just like in GENERIC), but it is never
started from rc.conf.

Some interesting things from the kernel config:
options         SCHED_4BSD
options         DEVICE_POLLING
options         HZ=3D2000
options         ZERO_COPY_SOCKETS
options         AHC_ALLOW_MEMIO
options         GEOM_BDE
device          apic

"options PREEMPTION" is NOT used.

PS! It's a Tyan Tiger MP motherboard (AMD 760MP based), but only one CPU =
is
installed (so far) and the kernel is a UP kernel.
