Hi,

I have a few nodes on a cluster with latest pve - running k8s in kvm's with Centos7

When running high cpu tasks, the node freezes without errors, only a hard reboot resolves this.
Hardware is different - so the same behavior on different hw hosts.

I've downgraded the kernel to 5.11.22-7 and now the systems are stable.

Does anyone encounter this issue ? Any known fixes ?
