나는 한동안(2-3년) lenovo x1 Extreme gen 1(현재 Ubuntu 20.04 기반의 최신 버전을 사용하고 있음)에서 팝 OS를 사용해 왔지만 최근에 다음과 관련될 수 있는 하드웨어 문제(노트북)가 발생했습니다. SSD는 새로 설치한 후에도 지속되는 ext4-fs 및 systemd-journald 오류로 인해 무작위로 충돌합니다. 아래에 몇 가지 스크린샷을 첨부했지만, 아래 로그 디렉터리에서 찾을 수 있는 오류 로그도 모두 넣을 것입니다.

dmesg에서도 온도 관련 오류가 많이 표시됩니다. 비록 이것이 얼마나 심각한지는 모르겠지만(임계값이 81C라는 점을 고려하면 약간 걱정스럽기는 하지만)

마지막으로, popos를 설치할 때(이 문제로 인해 지난 달에 여러 번 수행했습니다) 아마도 두 번의 시도 중 한 번은 추출 단계에서 설치 프로그램이 실패할 것입니다. 라이브 USB나 설치 설정을 변경하지 않고 몇 번 다시 시도하면 작동하므로 무작위 읽기/쓰기 오류처럼 보입니다. 설치 로그에도 입/출력 오류가 표시되는 것 같습니다. 주목할 만한 항목은 다음과 같습니다.

추가 정보:
또한 노트북과 함께 제공되는 몇 가지 메모리 진단 테스트를 수행했는데 그 중 어떤 오류도 반환되지 않았습니다(누군가 요청하지 않는 한 여기에 게시하지 않음).
Linux를 다시 설치할 때마다 잠시 후 문제가 다시 발생합니다(디스크를 최대한 비워두려고 하면 시간이 더 오래 걸릴 것 같지만). 또한 설치 시 "새로 고침" 옵션이 도움이 되지 않는 것 같아서 Linux를 완전히 다시 설치해야 했습니다.
수리 시도:
이 문제는 일반적으로 Linux를 새로 설치할 때 며칠 후에 다시 발생하며, 하드 드라이브에 얼마나 많은 콘텐츠를 넣었는지와 관련된 것 같습니다. 의도적으로 최소한으로 유지하려고 하면 충돌이 발생하기까지 시간이 더 오래 걸리는 것 같습니다. 마지막 충돌은 Python을 통해 약간의 집중적(수 100MB) 읽기 및 쓰기 작업을 수행할 때 발생했습니다.
Arch-linux 위키에 힌트가 있습니다(https://wiki.archlinux.org/index.php/Solid_state_drive/NVMe) 즉
Linux 4.10의 Samsung 드라이버 오류
Linux 4.10에서는 드라이브 오류가 발생하여 시스템이 불안정해질 수 있습니다. 이는 드라이브를 사용할 수 없는 절전 상태로 인해 발생한 것으로 보입니다. 최소 절전 상태를 비활성화하고 쓰기 오류를 방지하려면 커널 매개변수 nvme_core.default_ps_max_latency_us=5500[4][5]를 추가하세요.
내 것도 삼성(자세한 내용은 아래 참조)이므로 제안된 대로 수행했지만 도움이 되지 않은 것 같습니다.
SSD 업데이트는 없지만 주로 BIOS를 통해 모든 펌웨어를 업데이트했습니다. 이로 인해 몇 가지 다른 문제가 해결되었지만 이 특정 문제는 해결되지 않았습니다.
나는 하드웨어에 대한 지식이 거의 없고 내가 전혀 알지 못하는 임의의 커널 매개변수를 입력하고 싶지 않기 때문에 어떻게 진행해야 할지 잘 모르겠습니다.
필요한 경우 전체 로그를 업데이트할 수 있습니다.
답변1
NVMe 하드웨어 장치에 문제가 있는 것 같습니다. 복구 USB 이미지에서 부팅하고 NVMe 장치에서 실행해 볼 수 있습니다 badblocks. 또는 장치를 지우거나 테스트할 수 있는 삼성 진단 도구가 있는 경우 실행할 수 있습니까?
