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

Will you be able to make a fix for this so the minimum frequency won't have to be changed after every phone call? Right now I am using ULV kernel with the min at 250 because that kernel uses the lowest voltage at that frequency. I would perfer to use the XLV kernel and set the minimum frequency at 125 but having to change the frquency back to 125 after every call is too much of a hassle. Thank you again for your awesome kernels!
