    I have an ALR Revolution Q-SMP board with four P133 processors
    on it.
    I tried to run 2.1.97+IO-Apic patch, but it still won't work :-(

    I can run the 2.1.97 kernel fine with UniProcessor kernel.
    SMP_kernel compiles OK, but at booting it always comes to :

    CPU0: Intel Pentium 75+ stepping 0b
    Calibrating APIC timer
    ..... CPU Clock speed is 133.3200 Mhz
    ..... APIC bus clock speed is 533.3113 Mhz.
    Booting processor 1 eip2000 : Not responding
    Booting processor 2 eip2000 : Not responding
    Booting processor 3 eip2000 : Not responding

    The system then tries to boot further and finally hangs at :

    Kernel panic : IO-APIC + timer doesn't work !

    Any ideas ?
