Maybe you need to enable ACPI.

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

Change CONFIG_NR_CPUS to 8.

Hi ,
we compiled 2.4.23 for 2 cpus but we don't get Hyperthreading working.
with 2.4.20 and the machine, it work without probs.
Any ideas?
