Hi,

any idea why CPU frequency scaling doesn't work for 3.14.25-rt22 [1] and why it does work for 3.17.6 [2]?

Regards, Ralf

Because it's broken on 3.14 with realtime patch :)

Probably quite offtopic on this list since it's from aur and archaudio... Think it still works on 3.10-rt-lts

My apologies and yes, you are right, it works with the LTS linux-rt :).
