I have a server running Ubuntu 12.04. The current issue is the following:
* if I activate 2nd-stage powernap to poweroff (or 'shutdown -h' by using /etc/powernap/action), the computer will not wake when sent a magic packet.
* if however, I manually shutdown the computer (using shutdown -h from the console), the computer can be woken up with a magic packet without any problem.
I have no idea about the reason for this. I used previously powernap with 11.04 (or 11.10, I don't remember) and it worked correctly (the current installation is a clean one).
I have attached the powernap main config (with 2nd stage deactivated, but of course I ran the tests by activating it).
Note that the symptoms are the same if I try using suspend instead of poweroff/shutdown -h
