我正在运行配备 Core i7 的 Intel NUC（8i7BEH 套件）。以下是cat /proc/cpuinfo8 个逻辑核心中第一个的输出（为您提供有关我的 CPU 的信息）：

我注意到在我的 中/var/log/syslog，我收到了很多此类垃圾邮件：

根据时间戳，这种情况似乎每 5 分钟就会发生一次。以下是我安装的 Ubuntu 的版本信息：
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic
我不确定这些错误是否无害。即使无害，我也不希望打印日志。对我来说，这表明存在某种硬件问题。但这会导致我的系统日志大量更新，从而掩盖其他重要信息。有人能帮我找到解决潜在问题的方法吗？或者如果真的没有，也许可以解释一下原因，以及如何让日志静音？
