Медленная загрузка, возможно, связана с микропрограммой

В течение последних нескольких месяцев загрузка системы (двойная загрузка Windows-Ubuntu) выполнялась слишком долго (~ 3 мин). Я пытаюсь исправить это прямо сейчас, и мне очень мало везет.

Симптомы

От включения компьютера до появления Grub занимает около 1 минуты. Переход от Grub к экрану входа в систему для Ubuntu занимает около 1,5 минут.

То, что я попробовал

Я выполнил время системного анализа , который выводит:

Startup finished in 1min 22ms (firmware) + 3.807s (loader) + 1min 7.203s (kernel) + 1min 30.475s (userspace) = 3min 41.508s 
graphical.target reached after 11.713s in userspace

Я выполнил график системного анализа , который показал, что dev-fuse.device занимает на порядки больше времени, чем все остальное. Красная полоса проходит весь путь от экрана вправо.

Основываясь на некотором гуглинге, я полагаю, что файл /etc/fstab использует неправильный UUID для свопа, но я не думаю, что это так. Это мой /etc/fstab :

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sdb6 during installation
UUID=0e0a0e10-243f-4be1-b285-f231826bf1bc /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sdb2 during installation
UUID=5EC7-7108  /boot/efi       vfat    umask=0077      0       1
# /home was on /dev/sdb7 during installation
UUID=8226e8a2-cb20-438f-9192-f8100a06c172 /home           ext4    defaults        0       2
# swap was on /dev/sdb5 during installation
UUID=b492987e-be36-43a5-97cc-39779d160353 none            swap    sw              0       0

И это то, что я получаю для sudo blkid | grep swap :

/dev/sdb5: UUID="b492987e-be36-43a5-97cc-39779d160353" TYPE="swap" PARTUUID="98261e45-3e1b-4ca5-828a-f413cfcbf251"

На основании комментариев кажется, что swap не является проблемой. Вот еще несколько диагностических результатов.

Я имею в виду, что может стать причиной медленной загрузки. Любая помощь будет оценена.
