Here's my experience with the patch for the various suspend levels (all activated through /sys/power/state). It looks like there are problems activating the resume code.
standby:
never turns off screen. just seems to hang after hwsleep-0257. power light flashes. hitting power button causes power light to stop flashing but no resume happens. system is hung and powercycle req.
serial console output:
Stopping tasks: ===================================| hda: start_power_step(step: 0) hda: start_power_step(step: 1) hda: complete_power_step(step: 1, stat: 50, err: 0) hda: completing PM request, suspend PM: Entering state. hwsleep-0257 [15] acpi_enter_sleep_state: Entering sleep state [S1]
mem:
does stopping tasks and laptop powers down. power light flashes as if in suspend.
serial console output:
Stopping tasks: =================================|
hand typed continued console out:
hda: start_power_step(step: 0) hda: start_power_step(step: 1) hda: complete_power_step(step: 1, stat: 50, err: 0) hda: completing PM request, suspend PM: Entering state. hwsleep-0257 [15] acpi_enter_sleep_state: Entering sleep state [S3]
On resume it is as for standby.
disk (firmware): activates h/w suspend just fine. bios appears to resume properly (all progress meters hit 100%) but it never seems to pass control back to the OS (or, at least, the OS never completes the resume as per above situations)
serial console output:
Stopping tasks: =================================| Freeing memory: ....................| hda: start_power_step(step: 0) hda: start_power_step(step: 1) hda: complete_power_step(step: 1, stat: 50, err: 0) hda: completing PM request, suspend PM: Attempting to suspend to disk.
