我有一台运行 Ubuntu 20.04 的新 AMD 3400g PC。我在查看 dmesg 时发现这个信息重复了八次：
[ 5.534686] EDAC amd64: Node 0: DRAM ECC disabled.
[ 5.534688] 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.)
我怎样才能解决这个问题？

添加
blacklist amd64_edac_mod
到
/etc/modprobe.d/modprobe.conf
来抑制这些消息。
