잘못된 설명:
를 실행할 때 ltp alltest모든 테스트를 몇 번 반복한 후 컴퓨터가 응답하지 않게 되고 데스크톱 및 기타 프로그램이나 데몬이 정지되지만 Linux 커널은 살아 있으며 USB 포트에서 USB 마우스/키보드를 연결하거나 연결을 끊으면 string 라인 포트는 일부 드라이버 로그를 인쇄합니다.
dio30은 "좀비" 상태를 유발하므로 100개의 하위 작업을 분기하고 파일의 병렬 diff 오프셋에서 writev/ 를 호출합니다. readv다음은 디버그 직렬 예외 로그이다.

디버그 직렬 로그에서는 diotest6이 데이터를 스토리지에 플러시하는 동안 SSD가 사망했을 수 있다는 것만 알 수 있습니다. 하지만 이 오류의 원인이 무엇인지 모르겠습니다. 누구든지 이 오류에 대해 몇 가지 아이디어를 갖고 있습니까?
