Is expected, as the method doesn't exists in coreboot.
I'm working on a cmos acpi driver, allowing easy integration of that
method.
If you want you can implement a stub driver (emtpy function) in the
meantime.

I've no idea what the problem is.
Is there an ACPI expert here ?

More ACPI errors on Lenovo X201i

Hi Patrick,

commit "dbf5a5d0f8 ec/lenovo/h8/acpi: Fix ACPI error in _INI" fixed the
issue during boot, thank you.

Regarding the stub driver, I have no idea on where to start. If you
think it is worth your time and easy enough as an entry level task, I
would like to ask for some guidance and/or hints to something similar in
the code tree in order to get an idea on how to implement this feature.
If not, I will wait for your driver implementation as the issue seems to
be non-critical so far.

Cheers,
Matthias
