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.
