WOL does not work when using shutdown, but works with suspend (S3) and "halt -p"

[Rune Evjen]

Binary package hint: upstart

I am not sure whether this is the fault of upstart, or some other package, but the problem is:

Wake-on-LAN works in the following situations:

1) when suspending the system to S3 (using pm-suspend)
2) When issuing "sudo halt -p" from the command line.
Note: I have not tested WOL from hibernate

If I shut down the system from XFCE or by issuing "sudo shutdown -h now" I cannot wake up my system by sending a WOL packet from another computer.

I really want to avoid using suspend as suspend support seems a bit unstable on my computer running as a mythbackend.

I also understand that "halt -p" does not run the shutdown scripts in rc0, rc1 and rc6 which probably is not good for my system services.

But it seems like that somewhere during the shutdown scripts WOL is disabled.

I have tried setting NETDOWN=no in /etc/init.d/halt to prevent halt from bringing the network interfaces down.

I enable WOL with a script in init.d, here is the script:
#!/bin/sh
### BEGIN INIT INFO
# Provides: wakeonlanconfig
# Required-Start: $remote_fs $syslog
# Required-Stop: $remote_fs $syslog
# Default-Start: 2 3 4 5 S
# Default-Stop: 1 6
# Short-Description: Set up Wake On Lan
### END INIT INFO

ETHTOOL="/usr/sbin/ethtool"
DEV="eth1"
case "$1" in
start)
    echo -n "Setting $DEV to wakeonlan..."
    $ETHTOOL -s $DEV wol g;
    echo " done.";;
stop)
    ;;
esac

exit 0

The Wakeonlan script is run at the following runlevels:
locate wakeonlan
/etc/init.d/wakeonlanconfig
/etc/rc0.d/K20wakeonlanconfig
/etc/rc1.d/K20wakeonlanconfig
/etc/rc2.d/S20wakeonlanconfig
/etc/rc3.d/S20wakeonlanconfig
/etc/rc4.d/S20wakeonlanconfig
/etc/rc5.d/S20wakeonlanconfig
/etc/rc6.d/K20wakeonlanconfig
/etc/rcS.d/S20wakeonlanconfig

I suspect I have the same problem with my mythtv frontend computer,
after issuing "halt -p" I can wake the computer using WOL.

When using "shutdown -h now" or XFCE shutdown menu choice I am not able to wake up the computer using WOL.

I am unable to test S3 mode because suspend is broken on this computer.

Log files for the second computer are attached.

I used to have this problem only when shutting down from the command line (sudo halt or sudo shutdown -h now). It would work fine with the shutdown from the menu in 11.10 but, now that I've upgraded to 12.04, it isn't waking remotely.

I've never seen the -p variants of the commands, so I'm going to experiment with "sudo halt -p" and "sudo shutdown -hP now" when I get to work Monday. As of right now, my remote host isn't waking, so I have no way of testing different options until then. I'll also check the output of ethtool to make sure that the flag is set before shutdowns are issued.

Status changed to 'Confirmed' because the bug affects multiple users.

Hi, seems I get the same bug in 14.04 Suspend works, but not after shutdown.
