I have extracted and decompiled the ACPI tables (DSDT and SSDTs) from acpidump.
You can find the raw acpidump.out and the decompiled ASL tables in the
following Google Drive folder:
https://drive.google.com/drive/folders/1aTqLAnUhrTsPdpA8tfOFyRopG3P3DGnc?usp=drive_link

As far as I can see/understand there is no _DSM method defined under the
GPIO controller device (AMDI0030) or the \_SB.GPIO scope.

Under the _AEI method (defined in SSDT9 line 188-193), pin 21 (0x15) and
pin 24 (0x18) are defined as:

GpioInt (Edge, ActiveBoth, ExclusiveAndWake, PullNone, 0x0000,
    "\\_SB.GPIO", 0x00, ResourceConsumer, ,
    )
    {
        0x0015 // Pin 21 (Touchpad attention line)
    }

When triggered, they evaluate the _EVT method which calls:
Case (0x15)
{
    \_SB.PCI0.SBRG.HNC0 (0x15, Zero)
}

Since Arg1 is Zero, HNC0 executes the Else branch, invoking M009 and ATKM/ADTM,
which stalls synchronously for ~36 seconds when executed during the probe path at 
boot time.

Thanks,
Marco
