Not the reporter but having a similar issue. When the systemd package is updated my bond dies (with the "speed changed to 0 for port" message). Nothing that I have tried to restore the network connection worked short of a full reboot. I have attached my syslog showing what occurs during the upgrade.
I also see the following during this time: bond1: Warning: No 802.3ad response from the link partner for any adapters in the bond The LACP configuration on the switch is identical for all servers with bonds, but the only ones having this problem are the ones running bionic (trusty & xenial are unaffected). I will try to find some time to see if I can reproduce with a simple 'systemctl restart systemd-networkd' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824806 Title: Network stops working after systemd update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1824806/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
