Linux가 종료 시 멈췄습니다. 어떻게 해야 합니까?

Ubuntu 20.04()를 실행하는 컴퓨터를 다시 시작하려고 했지만 Linux 5.15.0-67-generic #74~20.04.1-Ubuntu검은색 화면에 오류나 경고 메시지가 계속 출력되고 종료되지 않습니다. 어떻게 해야 합니까? 강제 종료하려면 전원 버튼을 5초 동안 누르는 것이 좋을까요? 즉, 디스크 불일치가 발생합니까?

다음 시점부터 종료 메시지가 일반적인 메시지와 다르게 보이기 시작합니다.

여기서 의미하는 바 ......는 남은 줄을 생략했다는 뜻이고, 세로줄 2개는 :여러 줄을 생략했다는 의미입니다.

화면은 계속 작동합니다. 현재 다음과 유사하지만 약간 변경된 메시지가 반복됩니다.
