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=2000 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.
