예상치 못한 주말 정전 조사

오늘 아침, Fedora 22를 실행하는 내 컴퓨터가 꺼져 있었고 다음과 같이 검은색 터미널 IIRC에 전체 화면이 흰색으로 표시되었습니다.

[Rebooting] ...
System halted.

전원 버튼을 누른 채 재부팅한 후 이렇게 불필요한 재부팅을 일으키는 원인이 무엇인지 파악하고 싶습니다. 일부 로그를 보면 일요일 최소 14시까지 지속되는 것으로 알고 있습니다. 시스템에 더 많은 정보가 있나요? 어떤 프로세스가 종료를 시작했습니까? 커널 패닉, 스크립트, 어떤 사용자 등인가요?

하드웨어 문제나 자동 업데이트에 대해서는 알지 못합니다. 몇 년 된 데스크톱 컴퓨터이며 일부 크론 작업도 실행합니다. 최근 Fedora 22를 정리하도록 업그레이드되었으며 지금까지 훌륭하게 실행되고 있습니다.

를 사용하면 sudo journalctl -b -1systemd가 17시 36분경에 종료를 시작하고 5분 후에 종료 시퀀스가 ​​이어지는 것을 볼 수 있습니다.

또한 네트워크 관리자는 연결을 확인하고 같은 시간에 반복적으로 실패합니다. 다음은 당시 기록에서 발췌한 내용이다.
