删除系统日志中的ECC警告

Question

如何禁用有关ECC的这些警告？我没有ECC内存，所以在bios中也禁用了它，但是它仍然打印它。

如果您没有ECC功能的内存，则可以尝试查找并随后禁用此垃圾邮件模块：

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

会有相当多的*_edac*模块，但在您的示例中，罪魁祸首是amd64_edac_mod (正如错误消息中所暗示的)。

然后你要做的就是把这个模块放到黑名单文件中：

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

重新启动，哇！-模块不再被加载，错误也消失了。
