MCE(머신 검사 예외) 이해

하지만Ubuntu 16.04를 실행하는 새 노트북(KabyLake 아키텍처)에서 자주 정지되는 현상을 디버깅하려고 합니다.나는 다음 항목을 우연히 발견했습니다 kern.log.

kernel: [    0.041634] mce: [Hardware Error]: Machine check events logged

그 이후로 설치했지만 mcelog로그를 어떻게 해야할지 모르겠습니다. 내용은 /var/log/mcelog다음 과 같습니다

몇 가지 관찰 사항(틀렸다면 정정해 주세요):

  • 거의 모든 오류가 같은 페이지에서 발생하는 것 같습니다. ( ADDR fef1xxx)
  • 뱅크 6과 7만 영향을 받는 것으로 보입니다.
  • 모든 항목에는 "오류 오버플로" 및 "수정되지 않은 오류"가 포함되어 있습니다.

이것mcelog FAQ"메모리 오류는 낮은 비율로 수정될 것으로 예상되며 하드웨어 교체나 기타 조치가 필요하지 않습니다"라고 언급되어 있습니다. 로그 항목에는 실제로 어떤 조치를 취해야 함을 나타내는 "수정되지 않은 오류"라는 문구가 포함되어 있습니다.

내 질문은 다음과 같습니다

  1. 이러한 오류는 무엇을 의미합니까? 내가 그들에 대해 걱정해야 합니까?
  2. 이러한 하드웨어 오류로 인해 전체 시스템이 정지될 수 있습니까?
  3. 제조업체에서 노트북(또는 부품)을 교체해야 합니까?
  4. 제가 취해야 할 다른 조치가 있나요?

답변1

먼저, 귀하의 질문에 제대로 답변을 드릴 수 없을까 걱정됩니다. 또한 Dell XPS 13(9360)을 소유하고 있는데 동일한 MCE 메시지가 표시됩니다. 이에 대해 Dell 지원팀에 문의했습니다. 마더보드를 교체했지만 도움이 되지 않았습니다. 로그에도 동일한 메시지가 나타납니다. 어느 시점에서 그들은 그것이 거짓 긍정일 수 있다고 결론지었습니다. 그러나 그들은 그 원인이 무엇인지 모릅니다(mcelog/kernel/intel 문제?). 지원팀과의 커뮤니케이션은 계속 진행 중입니다.

<rant> 그런데 Dell 지원팀과 대화하는 것은 매우 불쾌한 경험이었습니다. 그들은 펌웨어 재설정, 자가 건강 테스트 실행 등과 같은 "표준" 솔루션만 제안하는 것 같습니다. 나는 기술에 정통한 사람과 이야기를 나눌 생각이 없습니다. </rant>

더 자세한 내용을 추가하면 Fedora 24에서도 동일한 문제가 발생하므로 Ubuntu와 관련이 없는 것 같습니다.

귀하의 질문에 관하여 :

이러한 오류는 무엇을 의미합니까? 내가 그들에 대해 걱정해야 합니까?

나는 모른다. Dell 지원팀에서는 이것이 거짓 긍정이라고 생각합니다.

이러한 하드웨어 오류로 인해 전체 시스템이 정지될 수 있습니까?

메시지 외에는 시스템이 정상적으로 작동하고 있습니다. 얼어붙는 건 또 다른 문제인 것 같아요.

제조업체에서 노트북(또는 부품)을 교체해야 합니까?

마더보드를 교체해도 MCE 문제가 해결되지 않습니다. 정지 문제를 해결할 수도 있지만,커널 업데이트를 통해 수정됨.

제가 취해야 할 다른 조치가 있나요?

아직 지원하지 않으셨다면 지원팀에 문의하세요. 더 많은 고객에게 영향을 미치는 것을 확인하면 실제 솔루션이 나올 수도 있습니다.

답변2

여기에 이미지 설명을 입력하세요.

지난 몇 가지 커널 업데이트(Fedora 25)로 부팅 시 팝업되기 시작한 것과 동일한 mce 오류가 발생했지만 이것이 팝업되기 시작한 정확한 업데이트가 무엇인지는 알 수 없습니다. 노트북은 DELL Inspiron 5567(Intel i5 7200U)입니다. 그러나 시작 시 시스템은 제대로 작동했기 때문에 이것이 어떤 이유로든 오탐지였을 것이라고 100% 확신합니다.
