the settings you have mentioned here are for the VM. I have a physical
machine. Let me go through these docs and give it a try.
Thanks.

First, we need the series of 3 patches at:
https://lore.kernel.org/all/20211012120903.96933-1-galpr...@amazon.com/

Thanks. I see the same behavior (i.e. no warning) with the patch.
