Cause

Dyskusji:
 
Błędy te występują, gdy moduł wykrywania i korekcji błędów (EDAC) odczytuje rejestry z chipsetu. W dzienniku ESM/BMC/IPMI/iDRAC możesz nie zauważyć żadnych błędów pamięci lub procesora.

 

Resolution

Rozwiązanie:

 

  • Umieszczanie sterownika edac na czarnej liście:
    • Lista modułów edac: 
      • # lsmod | grep -i edac
    • Weź dane wyjściowe i umieść je na czarnej liście:
    • Edycja '/etc/modprobe.d/blacklist.conf' ze swoim ulubionym redaktorem
    • Dodaj moduły na końcu pliku
    • Przykład:
      • blacklist i7core_edac
      • blacklist edac_core
  • Ponowne uruchomienie
  • Uruchom diagnostykę sprzętu
