每天有几次，平均有三次，我的系统崩溃并停止会话。没有迹象表明为什么会发生这种情况，它似乎是随机发生的。所有驱动程序都是最新的，没有其他驱动程序可用，也没有使用专有驱动程序。崩溃后，我可以再次登录，但会启动新的会话。
我使用的是 Thinkpad X1 Carbon gen 9，Ubuntu 22.04和X 上的 KDE 等离子。这是我的系统信息：
Linux dx1 5.15.0-40-generic #43-Ubuntu SMP Wed Jun 15 12:54:21 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
这些是syslog最近一次崩溃时的日志文件：

I am hoping someone can help me figure out what might be causing this issue and how to solve it.
