Can you provide those messages? (btw if you have a correctly working
firmware, simply saying "earlycon" will setup earlycon automatically)

Usually the lack of any output is caused by something failing prior to
the serial console being setup correctly. That specific Gigabyte
platform has various firmware releases, of which you should be running
the latest version to have the necessary ACPI tables.

A quick note, on ACPI. Disabling ACPI is not an optional thing. If you
turn it off, you will have a non-standard, completely untested, broken,
non-functional machine. Nobody tests any of the kernel sources with ACPI
disabled. In the future it won't be possible to disable it. Just say no
to turning off ACPI.
