我一直有一个问题，无论我怎样努力也无法彻底解决。
如果我的电脑已经运行了一段时间，然后我将 USB 插入端口，Ubuntu 就会完全冻结，然后重新启动。这种情况发生在多个 USB 驱动器上，所以不是某个特定的驱动器。此外，重新启动后，如果我插入同一个 USB 驱动器，它会正常工作，不会引起任何问题。但是，如果我等一会儿再试一次，USB 驱动器将导致冻结和硬重启。
以下是 /var/log/syslog 的片段：

我在 13:05 插入 USB，但这段时间没有任何记录。我还在运行服务器主板，所以我检查了主板的内部事件日志，事件发生时也没有记录任何内容。
问：我该怎么做才能解决这个问题或找出导致问题的原因？我有一些长期运行的程序，需要数周才能完成，而一个简单的 USB 就毁了一切。（我训练深度学习算法）
