cpufreq on-demand doesn't reach 1.0 GHz on zero CPU load
The CPUs switch between 1.3 and 1.5 Ghz but, even when load drops to 0 for a long time, they won't slow down to 1.0 Ghz. Using the "powersave" governor, we can manually force 1.0 Ghz: echo powersave > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
