It manages to boot with pci=noacpi, but then the touchscreen and touchpad don't work and for some reason the system freezes when I try to install GRUB.

Such duplicated entries are dumped without further processing. Unless we find further info, especially from ACPI standard, this is probably a WONTFIX.

So this system does have duplicated WMI devices, and they have different
functions. However, like what I said, WMI is not really a part of ACPI
specification, but a Microsoft specific standard. So there is no enough
information to know how do deal with these duplicated WMI devices.

It's benign; your BIOS has "duplicate WMI entries" within its ACPI tables and the kernel is reporting that.

Ignore it, and/or complain to your device's manufacturer (... and good luck with that).

Was this anything but just cosmetic? I looked at the patch and am running it now and nothing in the dmesg has changed (nor any functionality) except the messages aren't printed any longer.

During the architectural design of the WMI subsystem an assumption was made that there was a 1:1 mapping of WMI GUIDs (that is they're unique). This hasn't caused MAJOR functional problems, but this was proven wrong, as it's possible to fetch multiple BMOFs.

This change makes it so that if you have the wmi-bmof driver loaded on your system you'll be able to fetch all of the BMOFs. If you look in /sys/bus/wmi/devices, you should see more entries with this patch in place.

If the same GUID is used multiple times on a system for any reason beside wmi-bmof, that driver may need to be changed too.
