Thank you very much Craig for your suggestion.

Unfortunately, the command doesn't seem to mention anything related to 
wakeup on alarm:

yann at myth-backend:~$ cat /proc/acpi/wakeup

As a workaround, I have begun to setup WOL from another computer, as 
explained on the wiki.

But I must be very unlucky these days: the spare system has a problem 
with the onboard NIC. After 2 or 3 reboots, the network link is down, 
and I have to unplug an plug the cable in order to have it coming back. 
May be a problem with shielded cables, who knows.

Thank you anyway for your help and regards
