Lenovo T14 Gen1 CPU가 Linux에서 낮은 주파수에서 무작위로 멈춤

랩톱에 Fedora 33(kubuntu 및 ubuntu 20.04도 시도)을 설치한 후 다음 문제에 직면했습니다. 잠시 후 CPU가 무작위로 낮은 주파수(400MHz-800Mhz)에서 멈춰 속도가 빨라지지 않아 속도가 매우 느려집니다. 응답 시간이 느립니다.

cpupower 명령은 상태 코드 0을 반환하더라도 CPU 속도를 변경하지 않습니다.

intel_pstate와 Thermald를 비활성화해 보았습니다.

$ 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: 400 MHz - 4.90 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 400 MHz and 4.90 GHz.
               The governor "performance" may decide which speed to use
               within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 500 MHz (asserted by call to kernel)
boost state support:
 Supported: yes
 Active: yes
