刪除系統日誌中的 ECC 警告

  • September 2, 2020

如何禁用這些關於 ECC 的警告?我沒有 ECC 記憶體,所以在 bios 中也禁用了它,但它仍然會列印它。

[    4.697057] EDAC amd64: Node 0: DRAM ECC disabled.
[    4.697061] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
               Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
               (Note that use of the override may cause unknown side effects.)

如果您沒有支持 ECC 的記憶體,您可以嘗試查找並隨後禁用此垃圾郵件模組:

find /lib/modules/$(uname -r) -type f -name '*.ko' | grep _edac

會有很多*_edac*模組,但在您的情況下,罪魁禍首模組是amd64_edac_mod(如錯誤消息中所示)。

然後你所要做的就是把這個模組放入黑名單文件中:

echo "blacklist amd64_edac_mod" >> /etc/modprobe.d/blacklist.conf

重啟,瞧!— 不再嘗試載入模組並且錯誤消失了。
