ACPI Warning: Argument #4 type mismatch with 3.17.2 #101

Closed szpak closed 10 years ago

szpak commented 10 years ago

On Fedora 21 with 3.17.2-300.fc21.x86_64 on every bbswitch usage I see the ACPI warning in the system log. E.g.

kernel: bbswitch: version 0.8
kernel: bbswitch: Found integrated VGA device 0000:00:02.0: \_SB_.PCI0.GFX0
kernel: bbswitch: Found discrete VGA device 0000:01:00.0: \_SB_.PCI0.PEGR.GFX0
kernel: ACPI Warning: \_SB_.PCI0.PEGR.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20140724/nsarguments-95)
kernel: bbswitch: detected an Optimus _DSM function
kernel: bbswitch: Succesfully loaded. Discrete card 0000:01:00.0 is on

Everything seems to works fine anyway, but I report it just in case.
