我的这台笔记本电脑的网络一直存在问题，直到今天，在对一个不相关的问题进行故障排除时，我才dmesg -w发现这个问题不断重复出现：

（等等，直到永远）
网络大部分时候都正常，但我经常在浏览器中收到“网络已更改”错误（刷新通常可以解决此问题）。最近，尝试下载任何大型文件都导致多次中断。
还有谁见过类似的事情吗？可以给我一些指点吗？
我在这个网络上有许多其他机器（有线和无线），并且似乎都运行正常 - 只是这台笔记本电脑有问题......
干杯，阿德。

答案1
感谢 Neppomuk 提出的问题，今天早上我进行了更深入的挖掘 - 看起来这是一个陷入崩溃/重启循环的 Docker 容器。
一定要喜欢 Docker！
