      After installing the Sriov operator, reboot a worker node gracefully. The worker node can never come back online and stuck at the state "NotReady,SchedulingDisabled". The issue only happens on GCP.

      How reproducible:

      %100

      Steps to Reproduce:

      1. Use Cluster Bot to bring up a 3 masters + 3 workers OCP cluster on GCP with latest 4.13 ci build.
   - Send message "launch ci gcp,ovn" to Cluster Bot on Slack.
2. Install sriov operator via OLM and wait for it to complete
3. Gracefully reboot a worker node
   - oc adm cordon <node>
   - oc adm drain <node> --ignore-daemonsets --delete-emptydir-data --force
   - oc debug node/<node>
   - chroot /host
   - systemctl reboot

      Actual results:

      The worker node fails to become Ready.

      Expected results:

      The worker node is rebooted and becomes Ready.

      Additional info:

      We were running the ran profile CI in the cnf-features-deploy repo on GCP and it had broken for a while as the worker nodes couldn't come back online after reboot triggered by MCs. After investigation and more testings with cluster bot tool which will give you the same environment as prow/CI, it looks like related to sriov operator on GCP, without sriov, no issue to apply MCs/reboot. So we end up switching to AWS to unblock our CI.

More gathered info of the failed cluster is available here:
