I presume that it is NM that brings up eth0 in that case. So it seems that NM *does* realize that "auto eth0" alone isn't enough to count eth0 as being under ifupdown's control. So what I hypothesized in #4 was wrong. That's good to know. Yes, I'd guess that the present issue is related to the driver, atl1c. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1018933 Title: NetworkManager does not connect eth0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1018933/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
