Description NHO 2016-08-08 14:21:44 UTC

with command
>cpupower --cpu 0,1,2,3 frequency-set -g powersave
I expect output:
  Setting cpu: 0
  Setting cpu: 1
  Setting cpu: 2
  Setting cpu: 3

And correct governor reported from cpupower frequency-info.
Kernel gentoo-sources 4.7.0, intel_pstates governor.
cpupower 4.5.0 works correctly.

I see the same behavior here.  I'd guess that it affects the other scaling drivers as well, but at the moment I'm only able to test on 3 different ivy bridge i3/i5 cpus.

I have tested this on an older machine, cpu "Intel(R) Pentium(R) M processor 1.20GHz" with acpi-cpufreq scaling driver, same thing there, FYI
