Ошибка загрузки модуля ядра при загрузке

7

Я использую ubuntu 15.10 на ноутбуке Dell. Он отлично работает, но в последнее время я получаю медленное время загрузки (~ 1 минута). Поэтому я просматривал и когда читал файл /var/log/boot.log , я вижу следующую ошибку:

[FAILED] Failed to start Load Kernel Modules.
See 'systemctl status systemd-modules-load.service' for details.

С любой другой службой (кроме tftpd) работает отлично. Вот полный вывод:

что такое ошибка, влияет ли это на время загрузки и как оно должно быть исправлено?

Что такое «Не удалось загрузить модули нагрузочного ядра»?

Systemd считывает файлы в каталоге /etc/modules-load.d для модулей, загружаемых этой службой. Если модули, указанные в этих файлах, не присутствуют в каталоге /lib/modules для загружаемого ядра, появляется сообщение об ошибке «Не удалось загрузить модули ядра загрузки». Вот содержимое каталога /etc/modules-load.d из ls -lA

-rw-r--r-- 1 root root 119 Apr 20 17:01 cups-filters.conf
lrwxrwxrwx 1 root root  10 May 12 10:39 modules.conf -> ../modules

Захват данных из journalctl

В моем случае, вот соответствующая часть journalctl :

May 27 06:36:50 zanna-X205TA systemd-modules-load[176]: Failed to find module 'lp'
May 27 06:36:50 zanna-X205TA systemd-modules-load[176]: Failed to find module 'ppdev'
May 27 06:36:50 zanna-X205TA systemd-modules-load[176]: Failed to find module 'parport_pc'

Если вы делаете journalctl | grep modules , вы увидите, какие из них не смогли загрузить

В моем случае /etc/modules (на которое указывает symlink) пуст, но файл cups-filters.conf содержит ссылки на модули, которые бросали ошибки:

# Parallel printer driver modules loading for cups
# LOAD_LP_MODULE was 'yes' in /etc/default/cups
lp
ppdev
parport_pc

Отключение сообщения

У моего ноутбука нет даже параллельных портов, что неудивительно, поэтому мне не нужны эти модули. В любом случае они не могут быть загружены, поскольку они не были в /lib/modules/$(uname -r)

Я прокомментировал эти три строки (поместив # в начале строки перед именем модуля для каждого из них), и сообщение об ошибке исчезло.

Я не заметил никакой разницы во время загрузки.

TL; DR

  • проверьте journalctl , чтобы увидеть, какие модули не загружаются
  • прочитайте файлы в /etc/modules-load.d , чтобы найти ссылки на эти модули.
  • закомментируйте строки, которые указывают эти модули, чтобы ошибка исчезла (но перед редактированием сделайте резервную копию)
  • перезагрузите, чтобы узнать, не влияет ли это на время загрузки.
