Thanks for the reply. I've attached the disassembled dsdt from
"iasl -d dsdt.dat". I notice that the iasl output has "\_SB.PCI0"
whereas the acpidmp output has "\_SB_.PCI0". I'll try that with your
fake_ecdt patch.

I do see an error and two warnings when I let iasl compile the dsdt:

Compiling "dsdt.dsl"
dsdt.dsl 163: Method (_WAK, 1, NotSerialized)
Warning 2026 - ^ Reserved method must return a value (_WAK)

dsdt.dsl 2620: Field (ECR, DWordAcc, Lock, Preserve)
Error 1048 - ^ Host Operation Region
requires ByteAcc access

dsdt.dsl 2666: Method (_GLK, 1, NotSerialized)
Warning 2024 - ^ Reserved method has too
many arguments ( _GLK requires 0)

thanks,
Rich
