Trying to fix an GPU issue on a laptop, I followed the steps as described i=
n 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.
