Erreur du module de chargement du noyau lors du démarrage

8

J'utilise Ubuntu 15.10 sur un ordinateur portable Dell. Cela fonctionne bien, mais récemment, j'ai des temps de démarrage lents (~ 1 minute). Donc je regardais autour et quand je lis le /var/log/boot.logfichier, je vois l'erreur suivante:

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

Avec tous les autres services (sauf tftpd) fonctionnant parfaitement. Voici la sortie complète:

Quelle est exactement l'erreur, affecte-t-elle mes temps de démarrage et comment devrait-elle être corrigée?

Qu'est-ce que "Impossible de démarrer le chargement des modules du noyau"?

Systemd lit les fichiers du répertoire /etc/modules-load.ddes modules à charger avec ce service. Si les modules spécifiés dans ces fichiers ne sont pas présents dans le /lib/modulesrépertoire du noyau en cours de démarrage, l'erreur «Impossible de démarrer le chargement des modules du noyau» apparaît. Voici le contenu du /etc/modules-load.drépertoire dels -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

Capturez les détails de journalctl

Dans mon cas, voici la partie pertinente de 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'

Si vous le faites, journalctl | grep modulesvous verrez lesquels n'ont pas pu être chargés

Dans mon cas, /etc/modules(pointé par un lien symbolique) était vide mais le cups-filters.conffichier contenait les références aux modules qui lançaient des erreurs:

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

Faire disparaître le message

Mon ordinateur portable n'a même pas de ports parallèles, sans surprise, donc je n'ai pas besoin de ces modules. En tout cas, ils ne pouvaient pas être chargés car ils n'étaient pas/lib/modules/$(uname -r)

J'ai commenté ces trois lignes (en plaçant #au début de la ligne devant le nom du module pour chacune) et le message d'erreur a disparu.

Je n'ai cependant pas remarqué de différence dans le temps de démarrage.

TL; DR

  • vérifier journalctlquels modules ne parviennent pas à charger
  • lire les fichiers /etc/modules-load.dpour rechercher des références à ces modules
  • commentez les lignes qui spécifient ces modules pour faire disparaître l'erreur (mais veuillez faire une copie de sauvegarde avant de l'éditer)
  • redémarrez pour voir si cela fait une différence au démarrage
