Here's another panic I'm getting on a FreeBSD 5.2.1 machine, with 256 MB of RAM. Note, it is dual capable, but it is running with a single 450 Mhz Pentium II processor. The motherboard is a Tyan Thunderbolt. The kernel currently has SMP, APIC & ACPI enabled. Sometimes it will go two to three weeks before it crashes and other times it will only last a few days to a week, it seems to be random. I have 5.2.1 installed on two other dual processor machines and it seems to be working just fine. The biggest difference is of course, that these others have two processors and this one has one. Could this be a source of the problem? I've even tried compiling w/o APIC, ACPI & SMP w/o success. Ever since upgrading from 5.1 (which had 120 day uptime when it was updated) it has been unstable. So, I've enabled dumps on it to get a corefile to analyze, as well as running a kernel with the debug option on. Here are two core dump backtraces: > sudo gdb -k /boot/kernel/kernel vmcore.1 Password: GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.

Since this has been a problem, I've tried kernels w/o ACPI, SMP and APIC, with no luck, they've all eventually led to a lockup or panic.
