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?
