kern.log에 이러한 오류가 모두 표시되지만 이를 조사하는 방법을 모르겠습니다.
이 질문의 제목과 가장 관련이 있는 것이 무엇인지조차 잘 모르겠습니다.
AFAIU, 이는 하드웨어와 관련이 있을 수 있습니다. 그런데 어느 부분인지도 모르겠어요. 하드 디스크? 마더보드?

모든 USB 장치를 제거하고 DVD 드라이브를 분리한 다음 하드 드라이브의 SATA 케이블을 교체했습니다. 이제 새(작동하는 것으로 알려진) SATA 케이블이 포함된 하드 드라이브가 하나만 있습니다.
또한 smartmontools를 사용하여 하드 드라이브를 확인했습니다.
