Cause

Обсуждение:
 
Эти ошибки возникают, когда модуль EDAC (Error Detection and Correction) считывает регистры из набора микросхем. В журнале ESM/BMC/IPMI/iDRAC могут не отображаться ошибки памяти или ЦП.

 

Resolution

Разрешение.

 

  • Добавьте драйвер edac в черный список:
    • Вывод списка модулей edac: 
      • # lsmod | grep -i edac
    • Возьмем выходные данные и занесем их в черный список:
    • Редактировать '/etc/modprobe.d/blacklist.conf' с вашим любимым редактором
    • Добавьте модули в конец файла.
    • Пример:
      • blacklist i7core_edac
      • blacklist edac_core
  • Перезагрузить
  • Выполнение аппаратной диагностики
