Cause

Diskusjon:
 
Disse feilene oppstår når modulen for feilsøking og feilretting (EDAC) leser registrene fra brikkesettet. Det kan hende at du ikke legger merke til minne- eller CPU-feil i loggen ESM/BMC/IPMI/iDRAC.

 

Resolution

Løsning:

 

  • Svarteliste edac driveren:
    • List edac-moduler: 
      • # lsmod | grep -i edac
    • Ta utdataene og svartelist dem:
    • Rediger '/etc/modprobe.d/blacklist.conf'med din favorittredaktør
    • Legg til modulene nederst i filen
    • Eksempel:
      • blacklist i7core_edac
      • blacklist edac_core
  • Reboot
  • Kjøre diagnostikk av maskinvaren
