    SubjectACPI trouble (Was: Re: [patch] amd athlon cooling on kt266/266a chipset)
    Hello Dieter

    Yup, just a danish letter in my middle-name :-)

    Well, RedHat 7.2 does not look if apm or acpi is configured, it just
    uses -p unless the command run was 'halt' or 'reboot'.

    When running '/sbin/poweroff' from single-user, 'halt -i -d p' is the
    last command run by the halt script. The I get the message 'Power down.'
    from the kernel and my system just hangs here.

    When running /sbin/poweroff from runlevel 3 or 5, 'halt -i -d -p' is
    again the last command run, follwing this from the kernel:

    Power down.
    hwsleep-0178 [02] Acpi_enable_sleep_state: Entering S5

    And again my system hangs. Pressing the power button for 4 seconds turns
    off the computer (the BIOS is set to 'immediate power off').
    Ctrl-Alt-Delete or any other keyboard combinations do not work.

    Reboot works fine. APM poweroff also works flawlessly (but then I do not
    get the powersaving functions).

    In runlevel 3, the following modules are loaded (some are patched in
    from the iptables package. They should not cause this, as I can
    reproduce this without iptables configured/patched at all):

    I have tried different ACPI configurations, but I haven't been able to
    make any of them work.

    I have very little knowledge of ACPI, but I'll be happy to help (if this
    is not my fault of course - then I will apologize for taking your time
