Cluster version is 4.21.0-ec.3
cnfdg17 - gnrd-bc-tt & gnrd-bc-tr ptpconfigs, using cnfdg32 GM as clock source

Problem detected during regression testing - recovery test after rebooting node.

cloud-event-proxy is not showing any LOCKED events at all:
$ oc logs -n openshift-ptp ds/linuxptp-daemon cloud-event-proxy | grep -E 'event.sync.ptp-status.ptp-state-change.*LOCKED.*'
${code}
{code:none}
cloud-event-proxy reports FREERUN event.sync.ptp-status.ptp-state-change, while event.sync.sync-status.synchronization-state-change shows LOCKED:

    1.  Deploy SNO with gnrd-bc-tt & gnrd-bc-tr ptpconfigs
    2.  Reboot node
    3.  Observe cloud-event-proxy for event.sync.ptp-status.ptp-state-change event      

    LOCKED events are never reported

    event.sync.ptp-status.ptp-state-change reports LOCKED
