Moving this over to node/kubelet team to further investigate, since this doesn't look like a scheduler problem.
Comment 9 Andrew Beekhof 2021-04-19 00:37:22 UTC 
A reasonably simple improvement to kubelet's healthz checks would have prevented the node from becoming wedged.
Unfortunately there doesn't seem to be much interest merging the PR that implements it.
