    Hello,

    my box behaves a bit strange after "shutdown -h". The system performs a
    clean shutdown, but afterwards the front-side power button doesn't
    power-on anymore. After turning off power completely for 5 - 10 sec
    using the power supply's rear-side switch system boots again. I found a
    hint that this might be caused by a power supply that doesn't fully
    conform to ATX 2.01. Though this might be the real cause of my problem,
    I'd like to know if there is a workaround. Shutting down from an older
    Knoppix-CD (kernel 2.4.20 using apm) works fine, i.e. "front-side
    power-on" works. However, with 2.6 running on a SMP box there seems to
    be no way to poweroff via apm.

    Is there a way to let machine_power_off() behave like apm_power_off() on
    a SMP box?

    My system:
    kernel: 2.6.7-mm1 (same with other 2.4 and 2.6)
    CPU: 2 x Athlon MP
    board: Tyan Tiger MPX (S2466)

    TIA
