The cpuinfo_resource script looks for a frequency governors file. This file does not exist on all CPUs or architectures and the script exits with an error code and dumps a traceback when it tries opening the file.
Needs some error handling added.
This is from an ARM server where the governors file does not exist. The error is the same for any system without the cpufreq folder in sysfs.
