CPU core 0 throttled to min frequency

since some time i experience a weird behaviour (also now on 722)

cpu core0 getting throttled to min frequency, sample

and as im very sure i checked yesterday eve after updating to 7.2.2 its been on 3.4Ghz as i added this line on array startup (script)

bash -c 'for ((i=0;i<4;i++)); do cpufreq-set -c $i -u 3.4GHz -g performance; done'

to avoid whatever is happening always here

but seems "something" is triggereing here some cpufreq which shouldnt be ...

i double checked my scripts and cant see anything (besides upper info) which could be related.

attached also a syslog, cant see anything triggering this.
