The DSM failures, klog: HIGH Kernel message: [ 9.231078] ACPI Warning: \_SB_.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Integer], ACPI requires [Package] (20130517/nsarguments-95) klog: HIGH Kernel message: [ 9.237756] ACPI Warning: \_SB_.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20130517/nsarguments-95)
Seems to the mismatch Argument#4 that the graphic driver invokes the ACPI _DSM method, >From the ACPI spec, the arg3 type should be Package, but graphic driver >calling _DSM method with Integer and Buffer, So kernel complain about the mismatch the type of arg3. Fortunately, checking the Device-Specific Method _DSM that firmware implement, the Arg3 doesn't be used on firmware. So it should not be a problem of these mismatch if there are no any graphic functions fail.
