I noticed the following: this bug happens if I have lightdm and some other login manager installed (say gdm or slim). Then lightdm starts at boot even if it's not the default login manager. Then lightdm is shut down and the default login manager kicks in. After that, there seems to be a network configuration problem.
So the problem went away for me after I uninstalled lightdm. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/856810 Title: Boot hangs at "Booting system without full network configuration..."
