--- Comment #12 from KernelBug 3fdd1e5d@opayq.com --- I was reently told that OpRegion is something that Linux doesn't use, or something to do with modern harcware not using anymore, bottom line, it's not being used is what I gather...
To be honest I've never seen anyone talk about a solution anywhere for this, until I recently ran across using below, the cmd in your bootloader output, grub/lilo...
acpi_enforce_resources=no
I no longer any SystemIO range conflicts with OpRegion messages! :)
