Hi @EPZ
Sorry for the late response.
I think this problem was solved by locking cpu frequency witch cpufrequtils:
```
root@helios64:/etc# cat default/cpufrequtils
ENABLE=true
MIN_SPEED=1008000
MAX_SPEED=1008000
GOVERNOR=performance
```
After locking cpu frequency, check here few times:
```
root@helios64:/sys# grep . /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq
/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq:1008000
/sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq:1008000
/sys/devices/system/cpu/cpu2/cpufreq/scaling_cur_freq:1008000
/sys/devices/system/cpu/cpu3/cpufreq/scaling_cur_freq:1008000
/sys/devices/system/cpu/cpu4/cpufreq/scaling_cur_freq:1008000
/sys/devices/system/cpu/cpu5/cpufreq/scaling_cur_freq:1008000
```
