Desc

The many pod keep running, but ready is none.

pod/gpu-operator-1731802759-node-feature-discovery-master-5bcbfw57w   0/1     Running     0          18m

See logs, discovery "failed to read cpufreq directory" err="open /host-sys/devices/system/cpu/cpufreq: no such file or directory", but my OS this folder in the /sys/devices/system/cpu/cpu0/cpufreq.

Thank you.

Supplement:
This is cpupower result.

cpupower frequency-info
analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 1.20 GHz - 3.00 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 1.20 GHz and 3.00 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency: 1.80 GHz (asserted by call to hardware)
  boost state support:
    Supported: yes
    Active: yes
