Is it related to machineapi components or the cause is still unknown? Jusk asking since the bug is reported against Cloud Compute component.

Unknown.  It needs immediate triage and action.

- github.com/openshift/origin/vendor/k8s.io/apiserver/pkg/storage/value/encrypt/envelope TestIntermittentConnectionLoss: looks like network issue due to (failed to create connection to unix socket: @kms-socket.sock, error: dial unix @kms-socket.sock: connect: connection refused)

- github.com/openshift/origin/vendor/k8s.io/kubernetes/pkg/cloudprovider/providers/aws TestCreateDisk: just wrong order of tags:
        Tags: [{
+          Key: "kubernetes.io/cluster/clusterid.test",
+          Value: "owned"
+        },{
           Key: "KubernetesCluster",
           Value: "clusterid.test"
-        },{
-          Key: "kubernetes.io/cluster/clusterid.test",
-          Value: "owned"
         }]

- github.com/openshift/origin/vendor/k8s.io/kubernetes/pkg/controller/podautoscaler TestLegacyScaleUpUnreadyLessScale: the test needs to be updated (k8s 1.13 client-go patch implementation in generated fake clients changed a bit, this might be related)

- github.com/openshift/origin/vendor/k8s.io/kubernetes/pkg/kubelet/cm/devicemanager TestNewManagerImplStartProbeMode:  (E0402 19:35:19.844615   13396 plugin_watcher.go:120] error stat file /tmp/volume/device_plugin355861278/device-plugin.sock failed: stat /tmp/volume/device_plugin355861278/device-plugin.sock: no such file or directory when handling create event: "/tmp/volume/device_plugin355861278/device-plugin.sock": CREATE)
