During the run of the etcd certificate rotation tests, we've seen a panic invariant failing on the MCO pod:

{  pods/openshift-machine-config-operator_machine-config-daemon-nbpgc_machine-config-daemon_previous.log.gz:E0704 08:27:15.214245   11088 runtime.go:79] Observed a panic: "invalid memory address or nil pointer dereference" (runtime error: invalid memory address or nil pointer dereference)}

got it once today

  1. you can run the origin test suite with "openshift-test run "openshift/etcd/certrotation" 

    2. ???
    3. see the invariant result failing for that panic
