Hello all,

I always build a custom kernel from torvalds/linux.git as a training 
exercise, however since today a few of the special keys are not working.
(As in/de-creasing and muting sound). I get the following errors after 
pressing one of these buttons:

[   47.976253] ACPI: \_SB_.ATKD: Unsupported event type 0x32
[   50.846828] ACPI: \_SB_.ATKD: Unsupported event type 0x31
[   51.209026] ACPI: \_SB_.ATKD: Unsupported event type 0x30


I also find the following messages worrying:

The laptop is an Asus n61j and a version where the keys did work is:
01d5f3b598b18a5035426c30801adf65822dbd0c

my .config      : http://pastebin.com/cwar1Hk7
the whole dmesg : http://pastebin.com/9jmhLskD


Any pointers in how to fix this or if you require any more information
I'm glad to listen/supply. Are there any recent commits to the ACPI 
system I can take a look at?

Thank you!
