Bug Description
Ubuntu 12.04 LTS (release 12.04 according to lsb_release -rd). Machine has four NICs.
Set up a four-interface bond using the method outlined at http://
After a reboot things get interesting: Sometimes none of the slave interfaces come up and the bond therefore fails. Sometimes one or two of the interfaces come up, along with the bond. Leaving the machine for 15 minutes or so does not make for any changes. The interfaces that didn't come up at boot remain down. Unplugging, then replugging, cables makes no difference either. Restarting networking gets things back in their proper state.
Note that I tried setting this up under Debian 6.0.6 on an identical machine and one the same switch. It brings the interfaces up after a reboot, but doesn't pass any traffic. Arg!
