That's interesting. I looked into my old messages from the initial
install and found the same thing, so it's probably not the kernel version.
I have a couple of these boxes, so I'll swap the disk into another one and
see what happens. It may just be an issue with that particular system.
What does your /proc/cpuinfo say?
Thanks.

I'm finding this very, very odd - because we just installed two
dual-Xeon boxes tonight, straight from WBEL3.0 CDs, and they *both* have
hyperthreading working...
