<pre>Based on your acpidump for an Alienware 15 R3/0GY3V1, BIOS 1.0.8 11/12/2016
with GTX 1070, I found this in ssdt6.dsl:
Method (PGOF, 1, Serialized)
{
...
If (((\_SB.GGIV (0x01030009) == Zero) || (OSYS == 0x07D9)))
{
...
}
Else
{
LKDS (PIOF)
}
...
}
This is a common pattern that is known to give issues. The "LKDS" part seems to
cause issues, so you want to force the other code path. As OSYS is 2009 (set in
DSDT), try booting with:
acpi_osi=! acpi_osi="Windows 2009"
