Dear fwts folks,


Microsoft Windows showed the ACPI error below on a device with a 
coreboot based firmware [1].

> Stop Error Code=0xA5 (as Before), Parameter1=0xD, Parameter2=0xFFFFFA8004815A00, Parameter3=0x000000003353505F, Parameter4=0x0

Nico solved the problem [2]:

> Spec says if any object to control the power state exists, at least
> D0 and D3 must be supported. And it seems Windows complains about the
> missing D3 support: https://ticket.coreboot.org/issues/257
> 
> Windows reported `*** STOP: 0x000000A5` with the first parameter
> `0x000000000000000D` (refers to a missing ACPI object) and the
> third parameter `0x000000003353505F` which is the name of the
> object in ASCII, little-endian (`_PS3`).

It’d be awesome if you added a check for that to fwts. The log files are 
attached to the issue [1].


Kind regards,

Paul
