Cause

Discusión:
 
Estos errores se producen cuando el módulo de detección y corrección de errores (EDAC) lee los registros del chipset. Es posible que no observe errores de memoria o CPU en el registro de ESM/BMC/IPMI/iDRAC.

 

Resolution

Solución:

 

  • Incluya en la lista negra el controlador de EDAC:
    • Enumerar los módulos de edac: 
      • # lsmod | grep -i edac
    • Tome la salida y colóquelos en la lista negra:
    • Editar '/etc/modprobe.d/blacklist.conf' con tu editor favorito
    • Agregue los módulos en la parte inferior del archivo
    • Ejemplo:
      • blacklist i7core_edac
      • blacklist edac_core
  • Reiniciar por medio de un programa
  • Ejecutar diagnósticos de hardware
