All, I'm running SuSE 9.3, with all the updates made (Linux zarahemla 2.6.11.4-21.8-smp #1 SMP Tue Jul 19 12:42:37 UTC 2005 i686 i686 i386 GNU/Linux). I have motherboard that supports Hyperthreading and an HT Processor. However, SuSE still does not use both processors. dmesg shows the following: zarahemla:~ # dmesg | grep -i cpu Initializing CPU#0 CPU: After generic identify, caps: bfebfbff 00000000 00000000 00000000 0000041d 00000000 00000000 CPU: After vendor identify, caps: bfebfbff 00000000 00000000 00000000 0000041d 00000000 00000000 CPU: Trace cache: 12K uops, L1 D cache: 16K CPU: L2 cache: 1024K CPU: Physical Processor ID: 0 CPU: After all inits, caps: bfebfbff 00000000 00000000 00000080 0000041d 00000000 00000000 Intel machine check reporting enabled on CPU#0.

However, if I put in a Knoppix disk, both CPUs are detected, loaded and usable. I have an ASRock motherboard. Is this a bug? Am I doing something wrong? Thanks for any help you may be able to provide. -B
