Cause

Diskussion:
 
Diese Fehler treten auf, wenn das EDAC-Modul (Error Detection and Correction) die Register vom Chipsatz liest. Möglicherweise bemerken Sie keine Speicher- oder CPU-Fehler im ESM/BMC/IPMI/iDRAC-Protokoll.

 

Resolution

Lösung:

 

  • Setzen Sie den EDAC-Treiber auf die schwarze Liste:
    • Listen Sie edac-Module auf: 
      • # lsmod | grep -i edac
    • Nehmen Sie die Ausgabe und setzen Sie sie auf die schwarze Liste:
    • Bearbeiten '/etc/modprobe.d/blacklist.conf' mit Ihrem Lieblingsredakteur
    • Fügen Sie die Module unten in der Datei ein:
    • Beispiel:
      • blacklist i7core_edac
      • blacklist edac_core
  • Neu starten
  • Durchführen von Hardwarediagnosen
