klog: HIGH Kernel message: [ 6.952936] ACPI Warning:
\_SB_.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Integer], ACPI
requires [Package] (20130517/nsarguments-95)
_DSM is not called by BIOS, but called by device driver. In this case,
it is i915 who calls it. I am suspecting i915 does not call it
correctly.
However, this can be safely ignored in this case - Argument #4 is Arg3
in ASL, but it is not used at all on this system as below:
Method (_DSM, 4, Serialized)
{
Name (DRET, Buffer (0x04)
{
0x00
})
If (LEqual (Arg0, Buffer (0x10)
{
/* 0000 */ 0xE1, 0x75, 0x39, 0x6F, 0x82, 0x7A,
0x67, 0x4F,
/* 0008 */ 0x8B, 0x97, 0x15, 0xBE, 0xE0, 0x60,
0xBE, 0xDF
}))
{
If (LEqual (Arg2, Zero))
{
CreateWordField (DRET, Zero, F0SS)
Store (0x02, F0SS)
Return (DRET)
}
If (LEqual (Arg2, One))
{
If (LEqual (^^PEG0.PEGP.LNKV, 0x03))
{
Return (Zero)
}
Return (One)
}
}
Return (DRET)
}
