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.
