Comment 12 for bug 1872979

Issue is not dependent on PTP.
Was able to reproduce a second time.
This time on the 5th lock/unlock try with NTP rather than PTP enabled.

The common thread is collectd running early and experiencing network plugin 'Network Unreachable' failures.

Ideally, collectd should only start following configuration complete. However, since there is a collectd configuration manifest the collectd service file cannot have a After=config dependency directive as that will cause startup to hang ; collectd needs config but config needs collectd.
