...s in that case (it is never put into D3hot). I looked at the acpidump you sent and there is one thing that may explain the differences between Windows and Linux. Not sure if you were aware of this already, though. The power resource PGOF() method has this: If (((OSYS <= 0x07D9) || ((OSYS == 0x07DF) && (_REV == 0x05)))) { ... } If I read it right, the later condition tries to detect Linux which fails nowadays but if you have acpi_rev_override in the command line (or the machine is listed in acpi_rev_dmi_table) this check passes and does some magic which is not clear to me....

...accordingly. The methods itself do lots of things and it is hard to follow the dissassembled ASL which does not have any comments but there are couple of things that stand out where we may go into a different path. One of them is this in the PGOF() method: If (((OSYS <= 0x07D9) || ((OSYS == 0x07DF) && (_REV == 0x05)))) The ((OSYS == 0x07DF) && (_REV == 0x05)) checks specifically for Linux (see [1] and 18d78b64fddc ("ACPI / init: Make it possible to override _REV")) so it might be that Dell people tested this at some point in Linux as well.

I'm not sure what you are talking about. I'm taking specifically about the ((OSYS == 0x07DF) && (_REV == 0x05)) check mentioned by Mika which doesn't seem to depend on user input in any way.

4.20.0-rc3 nouveau/Quadro P2000 Mobile: runpm causing ACPI errors, lockups
So a new thinkpad: 01:00.0 VGA compatible controller: NVIDIA Corporation GP107GLM [Quadro P2000 Mobile] (rev a1) Hangs whenever I try to poke at the card. It starts happily enough with [ 3.971515] ACPI Warning: \_SB.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20181003/nsarguments-66) [ 3.971553] ACPI Warning: \_SB.PCI0.PEG0.PEGP._DSM: Argument #4
