Checked the latest CI test with the serialized patch and didn't see the same flakiness anymore on gcp, aws, azure: https://testgrid.k8s.io/redhat-openshift-ocp-release-4.6-informing#release-openshift-ocp-installer-e2e-gcp-serial-4.6 https://testgrid.k8s.io/redhat-openshift-ocp-release-4.6-informing#release-openshift-ocp-installer-e2e-aws-serial-4.6 https://testgrid.k8s.io/redhat-openshift-ocp-release-4.6-informing#release-openshift-ocp-installer-e2e-azure-serial-4.6
