Thank you for taking the time to report this issue and help to improve Ubuntu.
As documented at <https://wiki.ubuntu.com/LucidLynx/ReleaseNotes#Bonded%20network%20interfaces%20must%20use %20hotplug-style%20configuration>, you must use the hotplug-style configuration in /etc/network/interfaces; specifying the bond slaves in the bond interface stanza will not work. If you create the correct stanzas for eth1 and eth2, does this problem still occur? ** Changed in: ifenslave-2.6 (Ubuntu) Status: New => Incomplete -- bond_mode in /etc/network/interfaces ignored https://bugs.launchpad.net/bugs/559090 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
