Ubuntu 23.10
内核更新至 6.5.0-15 后，系统无法在启动时加载 zfs 模块。我以前遇到过这个问题，通过 dpkg-reconfiguring zfs-dkms 解决了。这次它似乎已经针对正在运行的内核进行了配置，再次重新配置没有任何效果。
我知道我可以通过关闭安全启动（我目前正在做的）或回滚到以前的内核版本（可能，实际上没有尝试，应该可行）来“解决”这个问题。

编辑：通过删除 zfs-dkms 解决了这个问题。结果发现我活在过去，它根本不需要，正如评论中指出的那样。
EDIT_2：系统在空闲约 30 分钟后完全冻结，重新启动后会加载到恢复模式并在启动登录管理器时冻结。通过回滚 zfs 快照修复。目前在日志中找不到任何有用的东西。不知道该怎么做。
