调整分区大小后，Ubuntu启动缓慢

我删除了交换分区，并创建了一个更大的分区。现在，我的开机时间比以前多了30秒钟。

这是输出systemd-analyze： Startup finished in 34.275s (kernel) + 8.404s (userspace) = 42.679s graphical.target reached after 8.397s in userspace

我检查以确保我的/etc/fstab文件具有用于交换文件的正确UUID（确实如此）。

这是输出systemd-analyze blame：

我在i5处理器笔记本电脑上使用ubuntu 18.04。

该启动通常需要5到10秒钟，但现在调整分区大小后已超过40秒钟。

编辑：这是输出journalctl -k -b：https : //pastebin.com/0ZAGvjit和dmesg启动后不久的输出：https : //pastebin.com/2fh9tExW

我在这里看到30秒的跳转来挂载文件系统分区：

[    3.092379] usb 1-8: Manufacturer: Samsung
[    3.102411] usbcore: registered new interface driver usbhid
[    3.102412] usbhid: USB HID core driver
[    3.804772] [drm] RC6 on
[   34.366616] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)

有任何想法吗？
