Subject: Re: [Intel-gfx] 3.19-rc1 errors when opening LID

I know how to use git... first I wanted to report errors because 
maybe it could be known problem or somebody else can come with 
quick patch even without bisetcing (like for other problems which 
I reported).

Anyway those acpi devices which are mentioned in log do not exist 
in 3.13 kernel (I do not see them in /sys/devices)

Any idea why 3.19 kernel create new acpi devices which 3.13 
kernel did not?
