Hi there,
Thank you for taking the time to look into this. This is actually not a
PowerNap bug, but rather, pm-utils (not really a bug though). pm-utils
ships a disable_wol script that, as its name says, disables wake-on-lan
when executing the pm-powersave (which powernap executes).
To fix this, you could either disable this script when pm-powersave
executes by removing the execution bit form the script. You'll find the
script at:
/usr/lib/pm-utils/power.d/disable_wol
Now, what should be done in PowerNap though, is to ensure WoL is enabled
when performing a poweroff/suspend action. I'll retarget this bug for
that.
Cheers.

** Changed in: powernap (Ubuntu)
Status: Triaged => Confirmed
** Summary changed:
- Powernap prevents waking from WakeOnLAN
+ Powernap should ensure WoL is enabled before Second Stage
** Description changed:
- I have a server running Ubuntu 12.04. The current issue is the
- following:
+ PowerNap should ensure that WoL is enabled before executing the second
+ stage action (poweroff/susped) as first stage action (powersave) will
+ disable WoL.
+
+ Note that powernap does not disable WoL, but rather, pm-utils ships a
+ script called disable_wol.
+
+ ============= Background ================
+ 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
