You need 2.5.X for ACPI/S3.

suspend-to-ram on A7V333

[Major A]

Hi,

I'm a total newcomer to ACPI, I tried it today because I want to get
the suspend-to-ram feature of my mainboard working. This is what I've
found out:

1. Using a plain linux kernel 2.4.19, the ospm-* drivers cannot be
   used as modules -- they create unresolved symbols. (This is not the
   case with 2.4.18.) Compiling them as static drivers works, and I
   get the relevant files in /proc/acpi, everything seems to work
   fine.

2. Pressing the power button creates an event which is dealt with by
   acpid, seems to work OK.

3. I can get use the S0/1/4/5 states by piping the corresponding
   number into /proc/acpi/sleep, and even S3 seems to work -- it
   prints a line saying something like "entering S3" (I couldn't read
   it because it was only a short time before the machine shut
   down). I suspect this is the S3 mode, with the power light
   flashing, but I cannot get the machine back out of suspend! If I
   press the power button or ctrl-esc (which I have set up as the
   keyboard-on combination) or even the "green button", it boots as if
   it hadn't suspended. Other keys or the (USB) mouse do
   nothing. Using the PS/2 mouse power-on feature doesn't help either.

4. If I disable the "suspend-to-ram" feature in the BIOS, the S3
   option disappears from /proc/acpi/sleep, as expected. The "fast
   resume" BIOS option doesn't seem to make any difference.

Anyway, does anyone have any experience with this? I can't try all
this under Windows (thank God), it seems that the computer just
forgets that it is supposed to be suspended only, whether that be a
BIOS or Linux problem.

One more thing -- I have a SCSI card with a BIOS in the computer,
maybe that makes a difference?

Hardware information: Asus A7V333 board with Athlon XP, Enermax power
supply (plenty of juice on +5VSB), PS/2 keyboard.

Thanks,

  Andras
