In your ULV kernel, it seems that after a call /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq is reset to 125000 from 124999 and after that the minimum frequency I can see in /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state is 250MHz instead of 125MHz

The only way to fix the issue is to do
echo 124999 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

after every call
