Public bug reported: Running systemd-networkd from systemd 237-3ubuntu10.23 on Ubuntu 18.04.2 I have one machine where, every time systemd-networkd restarts (ie every time there is an update to systemd) the bond0 interface stops working.
I see both physical interfaces go soft down and then come back again: Jun 21 07:28:24 odin.openstreetmap.org systemd[1]: systemd 237 running in system mode.

On most machines the cycle seems to take a bit longer and the interfaces reach a hard down start before coming back and in that case there seems to be no problem.
