To avoid fan noise, I set up my laptop such that it sets a low CPU
frequency upon boot via
for i in `seq 0 7`; do echo 120 >
/sys/devices/system/cpu/cpu$i/cpufreq/scaling_max_freq; done
in a startup script.
This all goes well until I

If this system has an Intel CPU, I'm afraid this is expected behaviour.
They no longer allow the OS to set an exact frequency, only a 'P-
state' (performance level). The Linux cpufreq driver for these
processors (intel_pstate) translates the requested frequency into a P-

Why not simply re-issue the request setting the performance-level after
resume?
You could at least suggest a script similar to the following
