Zoom을 사용하고 있었는데 이 메시지가 내 노트북의 /var/log/syslog에 나타났습니다. Lenovo Thinkpad X220i에서 Ubuntu 19.10을 사용하고 있습니다. 내 커널 버전은 5.3.0-42-generic입니다.

답변1
내 친구의 컴퓨터가 이런 일을 하기 시작했는데, 그는 그것을 노트북으로 사용하지 않고 TV에 연결하여 움직이지 않습니다. 눈에 띄게 먼지가 많으며 CPU 온도를 90-95C 범위로 유지하려고 노력하고 있습니다. 그는 이전에 먼지를 날려버렸고 그 후에는 킨젝션이 발생하지 않을 만큼 충분히 시원하게 유지되었으므로 그의 경우에는 그것이 해결책이라고 확신합니다.
나는 오래된 스레드를 괴사시키고 있다는 것을 알고 있지만 이런 일이 발생하면 냉각 시스템에 먼지가 있을 가능성이 높습니다. 또는 시스템이 설계상 과냉각되어 있습니다(일부 공급업체는 팬이 실제로 필요한 CPU에 팬 없는 설정을 선호하는 것 같습니다. 또는 충분히 뜨거울 때 팬을 낮은 속도로 유지하여 포기하고 약간 증가해야 합니다.)
