It says it will not use DSM - but did it maybe use DSM previously? The ACPI Warning seems to indicate that it did ... And just to complete the picture here's the _DSM from ACPI: Method (_DSM, 4, Serialized) // _DSM: Device-Specific Method { If ((Arg0 == ToUUID ("3e5b41c6-eb1d-4260-9d15-c71fbadae414"))) { Switch (ToInteger (Arg2)) { Case (Zero) { If ((Arg1 == One)) { Return (0x0001E7FF) } } Case (One) { If ((Arg1 == One)) { If (((S0ID == One) && (OSYS < 0x07DF))) { If (((DerefOf (Arg3 [Zero]) & 0xFF) == One)) { \GUAM (One) } Local0 = (DerefOf (Arg3 [One]) & 0xFF) If ((Local0 == Zero)) { \GUAM (Zero) } } If ((DerefOf (Arg3 [Zero]) == Zero)) { Local0 = CLID /* \_SB_.PCI0.GFX0.CLID */ If ((0x80000000 & Local0)) { CLID &= 0x0F GLID (CLID) } } Return (One) } } Case (0x02) { If ((Arg1 == One)) { Return (One) } } Case (0x03) { If ((Arg1 == One)) { Return (One) } } Case (0x04) { If ((Arg1 == One)) { Return (One) } } Case (0x05) { If ((Arg1 == One)) { Return (One) } } Case (0x06) { If ((Arg1 == One)) { Return (One) } } Case (0x07) { If ((Arg1 == One)) { IBTT = (DerefOf (Arg3 [Zero]) & 0xFF) Return (One) } } Case (0x08) { If ((Arg1 == One)) { IPSC = (DerefOf (Arg3 [Zero]) & 0xFF) If ((DerefOf (Arg3 [One]) & 0xFF)) { IPAT = (DerefOf (Arg3 [One]) & 0xFF) IPAT-- } IBIA = ((DerefOf (Arg3 [0x02]) >> 0x04) & 0x07) Return (One) } } Case (0x09) { If ((Arg1 == One)) { Return (One) } } Case (0x0A) { If ((Arg1 == One)) { Local0 = (LIDS << 0x08) Local0 += 0x0100 Return (Local0) } } Case (0x0D) { If ((Arg1 == One)) { Local0 = ((DerefOf (Arg3 [0x03]) << 0x18) | (DerefOf ( Arg3 [0x02]) << 0x10)) Local0 &= 0xEFFF0000 Local0 &= (DerefOf (DBTB [IBTT]) << 0x10) Local0 |= IBTT Return (Local0) } } Case (0x0E) { If ((Arg1 == One)) { Local0 = IPSC /* \IPSC */ Local0 |= (IPAT << 0x08) Local0 += 0x0100 Local0 |= (LIDS << 0x10) Local0 += 0x00010000 Local0 |= (IBIA << 0x14) Return (Local0) } } Case (0x0F) { If ((Arg1 == One)) { Local0 = GIVD /* \_SB_.PCI0.GFX0.GIVD */ Local0 ^= One Local0 |= (GMFN << One) Local0 |= 0x1800 Local0 |= (IDMS << 0x11) Local0 |= (DerefOf (DerefOf (CDCT [HVCO]) [CDVL]) << 0x15) Return (Local0) } } Case (0x10) { If ((Arg1 == One)) { Name (KSVP, Package (0x02) { 0x80000000, 0x8000 }) KSVP [Zero] = KSV0 /* \KSV0 */ KSVP [One] = KSV1 /* \KSV1 */ Return (KSVP) /* \_SB_.PCI0.GFX0._DSM.KSVP */ } } } } Return (Buffer (One) { 0x00 // . }) } I am not sure what makes it think that Arg3 is a buffer and not a package: IIRC Index (decoded C-style here as []) can apply to either.

BTW this one might indicate that somehow iwlwifi got powered down too somehow. It's at 00:14.3 Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10) so really shouldn't be affected, but go figure.
