Special keys not working after installing newest kernel

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:

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!

Can you run 'git bisect' to track down the patch that broke this for you? After doing that, please email the developers who wrote the patch and their mailing list (found using get_maintainer.pl) and they will work to resolve the issue.

thanks,
