Full Version: Debian + Hyper-Threading = Broken

Well I've been battleing this problem for some time now. It seems that Debian REFUSES to support Hyper-Threading. I've got SMP on, and I'm seeing 2 CPUs, but I should be seeing 4 in this dual xeon box.

From what I hear, it's those damn POSIX libaries I had a fight to the death with a few years ago...

Is anyone else having problems with this around here?

ACPI enabled in your kernel? (it must be and there's a specific option for HT). It's not enabled by default afaik.

Yup, that's what I thought it was too, but it's on.

After the upgrade to 2.4.25 from 2.4.24 last night, I'm now showing 4 CPUs.... very odd...

Nope, going from 2.4.24 to 2.4.25 would be an upgrade...

thats rather odd, I've had no problems seeing four cpus in all of the 2.4 kernels I've had on my kit I own in the uk...
