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!
