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 interpre=
ter does not support it, nor does the iASL compiler.
Once all the instances of this type of code are commented out, the DSDT com=
piles, 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, ope=
rator 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.
