    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.

    CPU0: Intel P4/Xeon Extended MCE MSRs (12) available

    CPU0: Thermal monitoring enabled

    CPU0: Intel(R) Pentium(R) 4 CPU 2.80GHz stepping 03

    per-CPU timeslice cutoff: 2926.18 usecs.

    Brought up 1 CPUs

    powernow: This module only works with AMD K7 CPUs

     

    And.

     

    zarahemla:~ # dmesg | grep -i mother

    SMP motherboard not detected.

     

    "top" and "hwinfo" also support that only on CPU is loaded. 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
