I ran into the problem that wake on lan is not working with freebsd and intel nic.
Shutdown the system with poweroff, WOL is not working.
if I comment out
/sbin/ifconfig -l | /usr/bin/xargs -n 1 -J % /sbin/ifconfig % down
in /etc/rc.shutdown, wake on lan is working.
the catch - after the reboot, the interface doesn't react (no IP - not even static - can be assigned). I've to poweroff the machine again (with ifconfig down) for the interface to work again.
Port LEDs stay on - with and without ifconfig down.
Here are the details:
