我的/var/log/syslog并且var/log/kern.log很快就充满了它冻结了我的计算机，甚至关机，重新启动都不起作用。我的 wifi 停止工作，即使我使用终端重新启动网络服务systemctl也不起作用。
这是与我的网络管理器错误相关的图像。我的网络管理器问题与此问题类似。
两个日志文件都充满了相同的 10 行消息。

我在以前版本的 Ubuntu 中没有这个问题。它从我升级到 20.04 LTS 开始。即使我已经重新安装了 Ubuntu，甚至我尝试升级我的内核，但它没有帮助。即使使用amdgpu而不是radeon没有帮助。我也尝试过添加nomodesetgrub。
这是我的PC的所有硬件相关信息，可能是信息所必需的。它有Integrated graphics.

这个问题中提到的答案只告诉要么删除日志文件。直到现在我也在做同样的事情，但它并没有解决问题。大多数时候会出现同样的问题，甚至关机也不起作用。所以，我曾经强行关闭，然后在恢复模式下重新启动以从 CLI 中删除日志文件。

正如这个问题中提到的。对它的回答只给出了限制syslogand大小的解决方案kern.log，但即使我限制了大小，但在那段时间我仍然会面临 wifi 驱动程序问题和风扇加速问题。它不会解决问题的根本原因。

看到日志消息后，我认为问题背后的原因是wpa_supplicant. 因此，我将 Ubuntu 上的无线守护程序wpa_supplicant从iwd. 它工作了两天，但后来我遇到了同样的问题System hanging and Wifi disconnection，但是这次没有记录任何大量数据/var/log/。
