That's probably unrelated. This shouldn't happen, so maybe file
a bug. Maybe it's something about systemd-networkd or NetworkManager
not starting (whatever you use)?

When sending out the email yesterday morning, I was trying to pin down
the versions where this happens. There has been at least one report
that this also happens with v246-stable and v247-stable, but no clear
confirmation that it happens with v248-rc tip.

Second goal is to find a reproducer and get a backtrace from when the
issue occurs.
