I can't be sure that it detects the 6 cores. I did get a dmesg prior
to rebuilding the world on it but I didnt get it off the box as I was
working on rebuilding the world. I tried rebooting w/ the old kernel
as well as, like I said, the 200809-CURRENT CD but it just hangs.

btw, this is a 4-CPU 6-core (4 Physical CPUs, 6 Cores each)

Yes. I read that thread. The OP said he had a chance to test the
6-core for a few hours. This box is in my hands for quite an
indefinite amount of time ;-)

Thanks.
