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.
