Subject: [BUG]: ACPI wakup devices (/proc/acpi/wakeup) don't wake the system anymore after hibernation
Hi,
I had always a issue with wake-up devices after suspend-to disk.
Scenario 1:
1) enable all devices devices: (echo "....." > /proc/acpi/wakeup), I have a script that does that
2) suspend to ram
3) hit a key on keyboard / mouse / send WOL magc packet, and system resumes in all cases
4) repeat the above, and all the same, good.
Scenario 2:
1) enable all devices devices: (echo "....." > /proc/acpi/wakeup)
2) suspend to disk
3) send WOL, doesn't wake the system, but should, and usb can't wake since it is powered off
4) power system on, let system resume from disk, works
5) suspend to ram
6) hit a key on keyboard / mouse / send WOL magic packet, nothing works.
I never got to the bottom of that issue, and just gave up, but not long ago,
and I sadly don't remember exactly when / what .config I had, it begin to work
I decided that this bug is fixed, and since I suspend to disk rarely, I assumed it works
But now, I discovered that this bug is back, and I don't know what to do
I tried 2.6.22, 2.6.21-rc7, 2.6.23-rc1, and all fail in same way.
Can you help me?
Best regards,
Maxim Levitsky
