任何帮助解决这个问题的帮助都会非常感激

当您在日志中收到错误消息时，最好的选择始终是找出根本问题是什么。

但是，如果一切似乎都正常，但你仍然在日志中收到垃圾邮件，那么可以采用以下方法过滤掉这些消息：

  1. 创建一个新文件/etc/rsyslog.d（这里我使用名称01-block-pcieport.conf）

    sudo touch /etc/rsyslog.d/01-block-pcieport.conf

  2. 输入以下内容01-block-pcieport.conf

    if $msg contains "pcieport 0000:00:1c.5" then { stop }

这将过滤掉相关的所有日志消息pcieport 0000:00:1c.5，并且您将无法再使用日志来排除该设备的故障。

因此，再次强调，强烈建议在过滤此类消息之前先找到根本原因。我想知道这是否是驱动程序问题？我认为您应该先调查一下这个问题。
