Hi,
I am getting the same issue.
Seems to me that the
/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq file is set
incorrectly to the highest value.
Hope the below is of use.

m...@titanic:~$ cat
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
2793000 2660000 2527000 2394000 2261000 2128000 1995000 1862000 1729000 1596000
1463000 1330000 1197000
m...@titanic:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
2793000 *********** wrong. Should be the lowest value - 1197000 for me
***********
m...@titanic:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
2793000
