Cause

설명:
 
이러한 오류는 EDAC(Error Detection and Correction) 모듈이 칩셋에서 레지스터를 읽을 때 발생합니다. ESM/BMC/IPMI/iDRAC 로그에 메모리 또는 CPU 오류가 표시되지 않을 수 있습니다.

 

Resolution

해결 방법:

 

  • edac 드라이버를 블랙리스트에 추가:
    • edac 모듈 나열: 
      • # lsmod | grep -i edac
    • 출력을 가져와서 블랙리스트에 추가하십시오.
    • 편집 '/etc/modprobe.d/blacklist.conf' 좋아하는 편집기와 함께
    • 파일 하단에 모듈 추가
    • 예:
      • blacklist i7core_edac
      • blacklist edac_core
  • 재부팅
  • 하드웨어 진단 실행
