Greetings:

I added the dmesg output within comment#36. Note that I made some mods to your
commands (e.g., I changed `cat /boot/initrd-4.12.14-94.41-default
>>/boot/instrumented_initrd-5.12.3-1-default` to `cat /boot/initrd-5.12.3-1
>>/boot/instrumented_initrd-5.12.3-1-default`) The debug statements you mention
are below. Please let me know if you have any questions, comments, or concerns.

{{{
> dmesg | grep 'ACPI Debug'

}}}

Kind regards,
