I have a Core Duo system (2 2GHz CPUs), that continually locks up (I

fine. When the system locks, I still have some keyboard control (num
lock lights, etc), but I can't seem to do anything else. I can't see
the screen, it goes black during that time. All my system

How can I debug (or help debug) this?
What if you disable just SMP but leave APIC enabled
(kern.smp.disabled=1)?
If I disable only SMP and leave APIC enabled, everything seems to work
fine. What other info can I give you?
I was able to get a backtrace, and a core from this. Here's some details:
