CNV cluster with 24+ nodes, 850 virtual machines

Windows 10 VM's seem to fall offline. When using the UI console - screen shows blank.

For some of the Windows logs we see:
Event log shows "Reset to device, \Device\RaidPort2, was issued. "

also pods are showing:
error killing pod: [failed to "KillContainer" for "compute" with KillContainerError: "rpc error: code = DeadlineExceeded desc = context deadline exceeded", failed to "KillPodSandbox" for "<sandbox_id>" with KillPodSandboxError: "rpc error: code = Unknown desc = failed to stop container for pod sandbox <sandbox_id>: failed to stop container k8s_compute_virt-launcher-<pod>.virtualmachines_<container_id>: context deadline exceeded"]

This seemed to happen after a mass windows update:

The guest was Windows 10 all updates.
Then these patches were applied to the Windows VM’s:
KB5005700
KB5005566
After this, 150 out of 700 went rogue and had the symptoms described above.
