Bug#883185: systemd-networkd: physical port in bridge stuck in "configuring", failing systemd-networkd-wait-online.service

[Bernhard Schmidt]

Package: systemd
Version: 235-3
Severity: normal

Hi,

after upgrading from Stretch to Buster the physical interface in my bridge
is stuck in "configuring", causing systemd-networkd-wait-online to stall
and eventually timeout.

This looks like https://github.com/systemd/systemd/issues/5043, although
I'm sure that I did not see this problem in systemd 232 in stable, unlike
the upstream reporter.
