After installing minimal Sparky 4.3.0, I dist-upgraded the system (openbox) to 4.4.0-1-amd64. My laptop is lenovo with i5 4200 processor.
When booting using kernel 4.4.0-1 cpu frequency is about 700 MHZ ,is not scalled and remind so despite running different applications.
When booting 4.3.0 it is properly scaled 0.8 to 3.1 GHz. I see it using - watch grep \"cpu MHz\" /proc/cpuinfo.
Did the same on bare debian. It is similar.
What I'm doing wrong?
