我有一个 Windows 10 / Kubuntu 22.04 双启动设置，两个操作系统分区都在同一个 SSD 驱动器上。
每周fstrim.timer都会触发fstrim.service在后台运行，结果我的系统以有趣的方式“崩溃”并变得无法使用，直到我进行紧急重启。
症状
- 尝试启动任何新的 GUI 应用程序均会失败。
- 某些应用程序（例如 Firefox）会完全冻结。
- 如果已经打开了 Konsole，我可以继续使用命令行。
- 尝试重新启动系统需要很长时间，同时在文本模式下显示以下消息（按下显示
Esc日志而不是普利茅斯屏幕后）：
A stop job is running for Discard unused blocks on filesystems from /etc/fstab
我通常在失去耐心后进行紧急重启。
我可以通过运行来重现上述情况sudo fstrim --fstab。在运行 fstrim 或执行时按 Ctrl+Ckillall -KILL fstrim没有任何反应。
先前研究
- https://ubuntuforums.org/showthread.php?t=2410364
在我从 Kubuntu 20.x 升级到 22.04 之前，也曾发生过同样的问题。现在 fstrim 在后台运行，而不是阻止系统启动，它现在每周都会在工作中随机骚扰我。 - https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1823721
不活动后标记为无效且没有明显的解决方案。
