• Activating profile using tuned showing CPU errors.

  tuned.utils.commands: Executing cpupower error: analyzing CPU 24:
  tuned.plugins.plugin_cpu: could not get current governor on cpu 'cpu24'
  tuned.utils.commands: Reading /sys/devices/system/cpu/cpu24/cpufreq/scaling_available_governors error: [Errno 2] No such file or directory: u'/sys/devices/system/cpu/cpu24/cpufreq/scaling_available_governors'
  tuned.plugins.plugin_cpu: ignoring governor 'performance' on cpu 'cpu24', it is not supported
  

  Examining /sys/devices/system/cpu/cpu*/cpufreq shows that cpufreq exists for all other 31 cores, but not for cpu24.
