    Subject[2.6.0-test5-mm1] Suspend to RAM problems
    Hello,

    I have got kernel 2.6.0-test5-mm1 on an Epox 8k9a9i Mainboard with
    KT400A and an Nvidia FX5200 using the nvidia-module and drivers.
    I use only onboard IDE and onboard ethernet.

    I want to be able to use Suspend to RAM with my machine. I tried
    APM and ACPI, both with no success. I also tried with no X11.


    1.) APM: (ACPI follows...)
    apm: BIOS version 1.2 Flags 0x07 (Driver version 1.16ac)

    Sep 10 12:02:55 localhost apmd[441]: Suspending now
    Sep 10 12:02:55 localhost kernel: hdc: start_power_step(step: 0)
    Sep 10 12:02:55 localhost kernel: hdc: completing PM request, suspend
    Sep 10 12:02:55 localhost kernel: hda: start_power_step(step: 0)
    Sep 10 12:02:55 localhost kernel: hda: start_power_step(step: 1)
    Sep 10 12:02:55 localhost kernel: hda: complete_power_step(step: 1, stat: 50, err: 0)
    Sep 10 12:02:59 localhost kernel: hda: completing PM request, suspend
    Sep 10 12:03:00 localhost kernel: hda: Wakeup request inited, waiting for !BSY...
    Sep 10 12:03:00 localhost kernel: hda: start_power_step(step: 1000)
    Sep 10 12:03:00 localhost kernel: blk: queue dfe03e00, I/O limit 4095Mb (mask 0xffffffff)
    Sep 10 12:03:00 localhost kernel: hda: completing PM request, resume
    Sep 10 12:03:00 localhost kernel: hdc: Wakeup request inited, waiting for !BSY...
    Sep 10 12:03:00 localhost kernel: hdc: start_power_step(step: 1000)
    Sep 10 12:03:00 localhost kernel: hdc: completing PM request, resume

    I pressed the power button at the machines case, but it comes back to
    life straight away. I also tried with apm --verbose --suspend and --standby,
    but with no change.


    2) ACPI
    Thanks to Andrew de Quincey I can boot with ACPI without
    problems and I can read out my temp and so on, but when I do
    echo -n "mem" >/sys/power/state
    the machine goes into sleep (STR) but crashes after waking up again.
    And an
    echo -n "S3" > /proc/acpi/sleep
    doesn't work at all.
    Also pressing the power button has NO effect. I think
    it does not generate an event.


    3) Questions
    What can I do to get STR working straight?
    Are these some stupid non-powersaving-aware drivers?
    What makes my system wake up from apm suspend? How to debug?
    I can see the CPU temp with ACPI, but how do I see the case temp?
    Do I need to change things in the system BIOS or does linux ignore that?



    Bye, claas
