We are testing the patch on our test environment. It seems that most nodes output this error on our cluster:

nsenter PIN:          0          0          0          0   Posted-interrupt notification event
nsenter NPI:          0          0          0          0   Nested posted-interrupt event
nsenter PIW:          0          0          0          0   Posted-interrupt wakeup event
nsenter grep: /proc/irq/2?/eff*list: No such file or directory
nsenter grep: /proc/irq/[23]?/smp*list: No such file or directory

The nodes are running on AKSUbuntu-2204gen2containerd-202310.04.0. While we still have dropping connections, we expect that the mitigation is not working properly.

Any thoughts that might help us?
