Resume problem (Motherboard: MSI 790GX-G65)

[Moore, Robert]

There are some nasty issues with this DSDT. Mainly, it uses "module-level" executable code, which has been illegal since ACPI 2.0. The ACPICA interpreter does not support it, nor does the iASL compiler.

Once all the instances of this type of code are commented out, the DSDT compiles, although there are 17 warnings. Some of them are potentially serious. Some examples:

dsdt.dsl  3499:                         Release (MLMU)
Warning  1099 -            Statement is unreachable ^

dsdt.dsl  9069:                         Add (Local1, 0x80)
Warning  1105 -                                   ^ Result is not used, operator has no effect

dsdt.dsl  6167:             Acquire (MUTE, 0x03E8)
Warning  1104 -                                 ^ Possible operator timeout is ignored


You probably should check if a new bios is available for this machine.

Interesting, the MB is an MSI, but the DSDT contains this:

    Name (VEND, Buffer (0x05)
    {
        "ASUS"
    })


I will email you updated DSDT source and the output from the compiler.
