Hi,

I want to get to the AML Debug object on boot. I'm setting the kernel
parameters appropriately:

	acpi.debug_layer=0xfffffff acpi.debug_level=0x2

debug_layer gets set just fine, however, debug_level always ends up
as 0xC. I don't get anything from the Debug object in the system log. Is
this some sort of bug?

Which kernel version are you using? I remember making changes to this at some point...

I'm on 5.0.0.
