Hi All,
I have 2 identical systems that both can run Freebsd 4.11 fine and have
done so for years. Yet I upgraded to RELENG6 and the system panics. I
validated that the hardware is fine so I've now gone through to the next
step of attempting to debug why the system panics.
I have the following system:
FreeBSD server 6.2-STABLE FreeBSD 6.2-STABLE #5: Sat Jun 16 16:16:50 EDT
2007 root@:/usr/obj/usr/src/sys/server i386
It seems to panic at random times which I can't really reproduce. I
have testsed using the following kernel configuratinos GENERIC, SMP,
GENERIC with acpi disabled but the system still panics. I'm stripping down
the kernel attempting to remove almost anything that could cause the
panic.
Here is my kernel configuation now:
