Greetings:

I think I was able to do what you wanted. I don't often add kernel parameters
so I edited the GRUB entry and then booted it. The following may indicate I did
it correctly (or not). I will attach the updated `dmesg` shortly. Thank you for
your help with this. If you need me to do it a different way, then please let
me know how.
