IASL complains about he same error in two different UEFI firmwares

[O. Hartmann]

Trying to fix an GPU issue on a laptop, I followed the steps as described in handbook,
chapter 12.17, debugging ASL/AML code.

I dumped on two different systems the ASL via

acpidump -dt as described and tried to recompile the result via iasl.


The outcome is a bit disturbing. IASL complains about the very same errors on two
diffrent systems.I'll show only one here, since the code block is identical.
