I have a Supermicro dual xeon 2GHz motherboard. I find that when
I run top, I have processes running on CPU0...3. When I run dmesg,
I find it lists 4 CPU's.

Has anyone else run into anything like this?

I also don't find this machine overly stable, it sometimes just
stops working.

Also, the CPU speed shows as ~800MHz here, but its supposed to be
2GHz. Any suggestions on where that comes from or how its measured?
