    It's likely that if your system supports ACPI, the APM implementation will
    not work, especially if you boot with ACPI enabled.

    What exactly does it do on wakeup?

    Would you please try the patch at:

    http://developer.osdl.org/~mochel/patches/test5-pm1/test5-pm2.diff.bz2

    against 2.6.0-test5 and report whether or not it works?

    Also, please try removing all modules before suspending and reinserting
    them after resuming.

    Do you have any of the following enabled:

    SMP?

    Preempt?

    APIC?


    > And an

    That should be:

    echo "3" > /proc/acpi/sleep

    But, please use the sysfs interface.


    Thanks,


    Pat
