ACPI BIOS ERROR: Buffer Limit? #31

I have a NUC11 Beast Canyon (the mini PC form factor w/the skull on front) and trying to get the LEDs going in Ubuntu 20.04. I've tried this project as well as many of the various forks and keep running into this:

[ 4352.076055] ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [CMD4] at bit offset/length 32/8 exceeds size of target Buffer (32 bits) (20201113/dsopcode-198)

[ 4352.076063] No Local Variables are initialized for Method [WMAA]

[ 4352.076065] Initialized Arguments for Method [WMAA]:  (3 arguments defined for method invocation)
[ 4352.076065]   Arg0:   00000000d9602656 <Obj>           Integer 0000000000000000
[ 4352.076070]   Arg1:   000000004c70c5eb <Obj>           Integer 0000000000000005
[ 4352.076073]   Arg2:   00000000078799a2 <Obj>           Buffer(4) 05 03 00 00

[ 4352.076080] ACPI Error: Aborting method \AMW0.WMAA due to previous error (AE_AML_BUFFER_LIMIT) (20201113/psparse-529)
[ 4352.076088] ACPI Error: AE_AML_BUFFER_LIMIT, wmi_evaluate_method (20201113/NUC_LED-267)

The correct GUID is there it just seems like it doesn't "take" the commands and I can't find any further information beyond this error message (output from dmesg after attempting to write to the kernel device). There are no LED settings in the BIOS besides the power button LED, and it has the latest BIOS. Presumably it works in Windows w/the Intel tool so I would assume the correct WMI things are in place to allow it to work. Any thoughts appreciated.

The kernel module currently in this repo does not support anything past a NUC 7. If you want that support you need to go to a downstream fork for now.
