Russ,
we just discussed this issue. It's most likely caused by a systemd
update where we restart journald in postinst.
That somehow seems to break the stdout->jounal forwarding, e.g. from NM
to its dhclient child process
If you restart NetworkManager.service, this will reset the state and fix
the issue.
By downgrading to -1, you triggered such a restart of NetworkManager, so
the downgrade is a red herring.

To reproduce the problem, you can simply run
systemctl restart systemd-journald.service
and then try to re-connect a NM connection and you'll experience the
same issue even with -1.

Otas, i'm not entirely sure if this actually the same issue you are having.

If you restart the network-manager service, is your problem gone?
If you not, could you get me a verbose debug log [1].


Thanks,
Michael
