Hi Dariusz Thanks for looking into it. The config looks like mine. p3p1 interfaces are Mellanox CX PCI cards and could it be due to modules are not loaded yet when bonding starts?
I have upgraded ifupdown to 0.7.47.2ubuntu4.3 version to get more logs. I have attached service --status-all output apt-cache for ifenslave and ifupdown dmesg http://paste.ubuntu.com/15175284/ ** Attachment added: "sosreport-SweAung.1337873-20160223104913.tar.gz" https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1337873/+attachment/4578447/+files/sosreport-SweAung.1337873-20160223104913.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337873 Title: ifupdown initialization problems caused by race condition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifenslave/+bug/1337873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
