| |
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?
