Compared the log with 4.8/4.9/4.10, no timeout and restart.

Comment 3 Jiří Mencák 2021-11-15 08:45:34 UTC

Thank you for looking Liquan!

The fix (https://github.com/openshift/cluster-node-tuning-operator/pull/287) merged 5 days ago on 2021-11-10, so your observation this is not fixed in
4.7.0-0.nightly-2021-11-08-025909 is correct.

I've tested on 4.7.0-0.nightly-2021-11-12-230709 (red build) and it is fixed there:

$ oc get clusterversion
