Hi,
There has also been an issue identified where HT will not be detected
correctly with 2.4.23 unless you apply a patch or set your number of CPUs to
8 instead of 2...

Please try the patch at
http://www.hardrock.org/kernel/current-updates/linux-2.4.23-updates.patch

as it contains this as well as other fixes.

Regards
James
