    SubjectProblems with the new "smp-calibration" routines
    Hello,
    I have some problems with the new linux-kernel (2.1.86, 2.1.87) concerning
    their new "smp-calibration" at the beginning of the boot-process (i don't
    have a better word, because i don't know what happens here ;)

    I have an Asus P65UP5 motherboard with a C-P55T2D pentium-CPU-card
    and two P166MMX Intel CPU's. The CPU's are overclocked, they run at 200MHz
    For the last 6 month (using 2.0.x, 2.1.5x) I have no problems, the machine
    runs very stable ! But I notice something strange: One CPU seems to be slower
    than the other, because of different bogomips. Here my /proc/cpuinfo
    under 2.0.33:

    processor : 0
    cpu : 586
    model : 4
    vendor_id : GenuineIntel
    stepping : 3
    fdiv_bug : no
    hlt_bug : no
    f00f_bug : yes
    fpu : yes
    fpu_exception : yes
    cpuid : yes
    wp : yes
    flags : fpu vme de pse tsc msr mce cx8 apic mmx
    bogomips : 398.13
    ^^^^^^
    processor : 1
    cpu : 586
    model : 4
    vendor_id : GenuineIntel
    stepping : 3
    fdiv_bug : no
    hlt_bug : no
    f00f_bug : yes
    fpu : yes
    fpu_exception : yes
    cpuid : yes
    wp : yes
    flags : fpu vme de pse tsc msr mce cx8 apic mmx
    bogomips : 331.78
    ^^^^^^
    Last week I've tried 2.1.86 (and today 2.1.87) but I can't boot the kernel,
    it hangs after the new "smp-calibration" with the following error message:
    ...
    16 000 00 1 0 0 0 0 0 0 00
    17 000 00 1 0 0 0 0 0 0 00
    Starting Kswapd v 1.23
    parport 0: PC-style at 0x278 [SPP,PS2,EPP]
    Ugh at c010a4a4
    divide error: 0000
    CPU: 0
    EIP: 0010: [<c010f0de>]
    EFLAGS: 00010097
    ...

    Running the CPU's at "normal" speed (166Mhz), everything works fine, but I
    don't want to do without the additional 34Mhz ;)

    Any hints ?
