Comment 1 Yu Qi Zhang 2022-07-05 17:15:50 UTC

I'm going to mark this as a blocker+. This is a regression in 4.11 that causes a potential panic in the MCO (machine-config-daemon pod specifically) if the user attempts to ssh into nodes, and can be an upgrade blocking issue. The fix is very simple and safe, so I think it's worth merging into 4.11.0
