--- Comment #2 from j.fikar@xxxxxxxxx ---
Well, I was trying the new CONFIG_NO_HZ_FULL and comparing it to the two old
CONFIG_NO_HZ_IDLE and CONFIG_HZ_PERIODIC. To my surprise the oldest (and I
thought most stable and most tested) CONFIG_HZ_PERIODIC causes problems with
CPU scaling.

On the other hand, I'm aware that CONFIG_NO_HZ_IDLE is the recommended default
and that there was a lot of recent development due to the new
CONFIG_NO_HZ_FULL. 

Anyway, I think it is a bug and not expected behaviour, right?
