It is still reproducible in Ubuntu 12.04. The "halt -i" command, which should shutdown all the network interfaces doesn't seem to work properly. To workarround, I've added this script to /etc/rc0.d & /etc/rc6.d:
$ cat K99wol_poweroff #! /bin/bash # The network interface must be shutdown manually for Wake-on-Lan to work ifconfig eth0 down -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/576110 Title: WOL not working: eth0 not properly taken down when network-manager is stopped Status in “network-manager” package in Ubuntu: Confirmed Bug description: Binary package hint: network-manager 1) The release of Ubuntu you are using: Problem occurs in two different laptops; one running Ubuntu 9.10 and the other Ubuntu 10.04. 2) The version of the package you are using: Ubuntu 9.10: network-manager 0.8~a~git.20091013t193206.679d548-0ubuntu1, Ubuntu 10.04: network-manager 0.8-0ubuntu3. 3) What you expected to happen: When network-manager is stopped (e.g. when I shutdown Ubuntu) I expect both my eth0 (LAN) and eth1 (WLAN) interface to be properly brought down during the process. To be more precise, I expect syslog reporting something like: May 5 02:14:31 pentium NetworkManager: <WARN> nm_signal_handler(): Caught signal 15, shutting down normally. May 5 02:14:31 pentium NetworkManager: <info> (eth0): cleaning up... May 5 02:14:31 pentium NetworkManager: <info> (eth0): taking down device. May 5 02:14:32 pentium kernel: [ 711.888429] tg3 0000:01:00.0: PME# enabled May 5 02:14:32 pentium NetworkManager: <info> (eth1): taking down device. May 5 02:14:32 pentium NetworkManager: <info> exiting (success) 4) What happened instead. The above syslog is only reported when I had deactivated eth0 manually before stopping network-manager (by means of bringing network-manager to sleep, disconnecting the active eth0 connection or by physically removing the ethernet cable). If I leave the eth0 connection activate during stopping network-manager, it is not brought down properly: May 5 02:17:15 pentium NetworkManager: <WARN> nm_signal_handler(): Caught signal 15, shutting down normally. May 5 02:17:15 pentium NetworkManager: <info> (eth1): taking down device. May 5 02:17:15 pentium NetworkManager: <info> exiting (success) 5) Why should this be fixed? Not bringing the eth0 interface down properly, effectively leaves it in an undefined state. This disallows me to use the WOL(wake-on-lan) functionality of the ethernet chipset. Currently I have to disable the network-manager completely as work-around, because I typically have no physical access to the machine (it is part of an unreachable measurement setup). WOL essentially is a simple and reliable system that can be very useful. Enabling it in BIOS and in the OS (e.g. 'ethtool -s eth0 wol g') should do the trick. As little things like this one really complicate matters, I think solving it makes many lifes a lot easier. : ) Thanks in advance anyway!
