I'm using NetworkManager and have the same problem: The network doesn't start and the reason seems to be because eth0 doesn't get the IP address. After I run either "sudo /etc/init.d/networking restart" or "sudo ifdown -a && sudo ifup -a" everything works fine. Part of the output is:
There is already a pid file /var/run/dhclient.eth0.pid with pid 134519072 My network setup worked before in Gutsy. -- [hardy] networking and ifplugd services not started when booting or resuming https://bugs.launchpad.net/bugs/213937 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
