Comment 11 for bug 440179

Seeing the same as Simone F. in #5 (note: /etc/init.d/networking start does work)

Seeing output of "initctl list | grep network" as Jon Watte (#9) ... but not the other things (e.g. ifup workin as expected. nothing in /var/log/boot)

meanwhile starting/stopping each interface manually as follows works too :
sudo service network-interface stop INTERFACE=lo

so i guess using the service command invokes another (broken) script than /etc/init.d/networking which works fine. this really shouldn't happen on a lts release
