Cause

討論：

當錯誤檢測和糾正 （EDAC） 模組從晶片組讀取寄存器時，會發生這些錯誤。您可能不會在 ESM/BMC/IPMI/iDRAC 記錄中注意到任何記憶體或 CPU 錯誤。

 

Resolution

解決方案：

 

  • 將 edac 驅動程式列入黑名單：
    • 列出 edac 模組： 
      • # lsmod | grep -i edac
    • 取得輸出並將其列入黑名單：
    • 編輯”/etc/modprobe.d/blacklist.conf' 與您最喜歡的編輯器
    • 在檔案底部新增模組
    • 範例：
      • blacklist i7core_edac
      • blacklist edac_core
  • 重新啟動
  • 執行硬體診斷
