#0 -1 »  Certains ports USB ne se montent pas et Ubuntu ne s'éteint pas » Le 16/07/2014, à 06:12

Bonjour,
Je cherche à résoudre une panne complexe : depuis une extinction prolongée en juin de mon PC en Lucid 10.04, j'avais perdu le réseau local et internet; après moult bidouilles, je perdais des USB (disques externes, cartes SD sur un dock USB, clés USB...) mais pas le clavier ni la souris ni un joystick, de plus Ubuntu était lent et ne pouvait s'éteindre (message final : mount is busy, killing alla applications fail...). J'ai essayé le passage en Precise 12.04: ordi moins lent, mais toujours pas d'USB ni de sons, ni de reboot simple. Je passe en 14.04 : toujours pas d'USB (sauf clavier, souris), reboot simple bloqué comme l'extinction.
Ma config : core: AMD 64 Fx6100 6 coeurs AM3+ , CM : MSI 990FXA GD65, carte graphique Asus GTX 550TI 1Go, RAM Corsair DDR3 1600 8Go, Disque SSD de 120 Go Corsair Force GT (où est installé Ubuntu), 2 disques WD 2 To + 1 de 500 Go (tous en Ext4)
Je tente de faire un lsusb : le terminal se bloque (alors que cela marchait en 12.04, indiquant que seul les ports du clavier, de la souris, du joystick étaient détectés). Je suis  perdu..

Merci,
Je pensai aussi que c'était matériel, mais lors de l'essai en live-disk de Trusty, tout marchait bien : reconnaissance des disques en USB, montage de périphériques spontanés... L'installation de la 14.04 a été difficile, a nécessité l'emploi d'un disque Boot-repair pour le Grub, mais une fois installée, la 14.04 n'a pas réparé les problèmes. Chose curieuse aussi, le boot-repair une fois utilisé s'éteignait correctement, mais après utilisation de la 14.04 installée, même le boot-repair ne s'éteint plus et ne monte pas les disques USB accessoires. Comme j'ai fait finalement des mises à niveau entre chaque versions, il doit y avoir un fichier ou un paquet corrompu, ou un blacklist qui persiste dans la racine et qui provoque la panne., mais quoi ??

UP?
Bon, j'ai fait des manips pour avancer : comme la 14.04 semble très sensible à l'affichage, j'ai réinstaller le pilote nvidia en purgeant tout ce qui pouvait interférer (notamment les couches Wine) et installant le pilote 331. Après une extinction de plus de 24h de la machine, j'ai eu une session impec : tous les USB reconnus et l'arrêt shutdown OK. Mais au redémarrage, les problèmes reviennent : les ports USB sur lesquels je tente de brancher des disques externes ou clefs USB ne sont pas reconnus et "lsusb" est bloqué (????) . Curieusement, lorsque qu'un des disques non / est monté en sda , le problème est présent (/ est alors en sdc1) . J'ai pourtant fait et refait boot-repair, mais cela ne change rien. A croire que quand la machine est chaude, elle ne peut plus s'arrêter et ne reconnaît pas les disques en USB. Pourtant, le proc et la carte vidéo ne dépassent pas les 45°, et il n'y a pas de poussières (le proc est refroidi par un watercooling). Il y a peut-être un bug entre les disques : je me souviens avoir indiquer, lors d'une réinstallation de Lucid, un point de Grub sur ce disque qui se met en première place dans la fenêtre de "Disques" (du Dash, Palimpset n'existant plus) alors que Ubuntu est installé sur un autre (le SSD), mais ayant purgé Grub et le réinstaller correctement à l'installation de Trusty et fait Boot-repair, je pense que cela ne doit pas interférer.

Çà parait compliqué roll , mais je donne des infos pour essayer d'avoir de l'aide. N'ayant pas de disques USB, je ne peux pas faire de sauvegarde... Quelqu'un peut-il m'aider?

Bonsoir,
Après une réinstallation le Lucid 10.04 parès un problème réseau m'empêchant une mise à niveau, le démarrage d'Ubuntu est très lent: Plymouth est lent à lancer l'invite de login et après avoir inscrit le mot de passe, il apparait un message : Power Manager est toujours en cours d'éxécution, et je dois attendre pour que le bureau de Gnome apparaisse, avec aussi un retard d'affichage des tableaux de bord. Les logiciels mettenat aussi beaucoup de temps à s'ouvrir. C'est malheureux, car avant la panne, la machine était ultra rapide. Lors de la réinstallation, j'ai eu quelques difficultés avec le pilote Nvidia dont le pilote propiétaire est utilisé , mais la lenteur était déjà présente lors de l'affichage en basse résolution. La machine est rapide pourtant (AMD 64 6 coeurs, 16 Go de RAM, carte vidéo MSI 990Fx...)

Merci Nam62, je vais voir rapidement les effets de ce tuto. Curieusement, après avoir "customizer" Grub, l'ordi s'est montré plus rapide, mais après un blocage lors d'un téléchargment sur la logithèque (le système parait instable) et donc un reboot, la lenteur est revenue. A suivre.

@ Korak: justement, j'essaye d'avoir une bonne config qui marche pour la mettre à niveau. Par contre, je vois que le noyau est toujours mis à jour (actuellement Linux Image xxx-62)

Merci pour votre aide

Ben çà marche pô... sad  Tojours ce message "power manager en cours d'éxécution" et lenteur à l'ouverture de Gnome et des autres logiciels.

Je ne pense pas que le Power Manager soit le seul en cause. Autre symptômes : la machine ne reconnait pas un dock en USB, ni les cartes mémoires dessus, ni un lecteur externe en USB3; de plus il plante à l'ouverture du contenu d'un disque interne : problème de mémoire? d'affichage?

Ce n'est pas un portable mais un ordi fait maison, qui marchait au top avant cette panne de réseau qui n'a pu se lancer après une extinction prolongée. La réinstallation s'est faite à partir d'un Alternate 10.04.
Autre symptôme : le test du système (Checkbox) ne peut rassembler les informations....

Désolé de ne pas répondre si tôt, mais j'ai du m'absenter.
Les diverses manoeuvres n'ont rien changé, toujours aussi lent. Encore un fait surprenant : en essayant un live cd de Precise, corrompu apparemment car le disque comporte des erreurs, j'ai fait un memtest qui n'indique pas d'erreur et en rebootant : pas de problème...?? rapidité, reconnaissance des disques, ouverture des logiciels rapides... Difficile à comprendre tout çà.

Mon fstab me parait erroné : le swap n'est pas à sa place, il ne fait pas mention de sda qui contient / , ne monte aucun disque et ne correspond pas à mtab.
fstab:

# /etc/fstab: static file system information.

Le 1 de la ligne UUID=42579596-5332-4571-957c-be5efcb78887 /               ext4    errors=remount-ro 0 1 était déjà inscrit, j'ai diminué l'espace, mais je pense que cela n'a pas d'effet.
Je vais essayer de bidouiller avec disk-manager.

J'ai modifié fstab et mtab par Disk-manager. L'ordi redémarre mais toujours le même bug.
Je crois savoir d'où vient la panne : au tout début, après cette autre panne réseau liée à une extinction de la machine pendant 3 semaines, j'ai essayé d'installer Precise après avoir télécharger l'image iso sur un Mac, mais l'installation n'a pu se faire, le disque comportant manifestement des erreurs, j'ai donc réinstaller Lucid et depuis ce bug de lenteur persiste. par contre, quand je lance le disque corrompu de Precise, même pour le tester, et reboot après , Lucid fonctionne parfaitement, j'en conclue que le disque Precise a installé quelques données qui empêche Lucid de fonctionner normalement, mais alors en connaitre le détail... gros mystère. je profite du bon fonctionnement pour graver une bonne image d'une nouvelle version.

Question intéressante, Moko138. En fait j'ai depuis longtemps été attiré par autre chose que Windows. J'ai commencé l'informatique en 1989 avec le Dos qui était facile et intéressant à l'époque, mais l'évolution de Microsoft, surtout dans ce but commercial qui l'anime, m'a fortement déplu et depuis XP je cherchais autre chose, j'ai essayé Mandrake (ne connaissant pas Ubuntu) et j'étais un peu dérouté, trop formaté par Windows et obligé, professionnellement parlant, d'utiliser XP au bureau; puis, après une panne matérielle de ma machine à domicile que j'utilise pour le loisir, j'ai installé Karmic Koala pour découvrir Linux, fortement aidé par la Communauté qui est géniale pour les débutants, et pour les autres aussi, j'ai mis du temps pour passer à Lucid qui marche très bien, sauf après un arrêt prolongé (même panne qu'il y a deux ans), et je mets du temps à passer aux autres versions (ayant comme adage: " pourquoi changer quelque chose qui marche?"). Mais le temps me manque pour améliorer mes connaissances de Linux, aussi je cafouille pour réparer un problème comme celui de ce post. Je profite de cette session qui marche comme citée en #16 pour télécharger et graver plusieurs versions Live-CD et Live-USB pour mettre à niveau Lucid vers Precise et un peu plus tard Trusty, autant profiter des améliorations. Mais c'est vrai que je me fais mal à Unity, préférant une interface dépouillée comme Gnome (d'ailleurs que j'avais sous Mandrake).

Voilà, voilà. J'attends le moment de mettre [RÉSOLU] au titre wink

Amitiés

Merci pour tous ces conseils. Pas question d'abandonner Linux, j'aime trop. J'ai confondu le Mac de mon épouse sur lequel nous avons mis 16 Go, mon desktop n'a effectivement que 8 (je l'ai monté il y a déjà deux ans, çà passe vite). J'ai déjà utilisé Disk-manager auparavant et il fonctionne très bien chez moi, malgré les critiques recueillies sur le Forum. Le Fstab obtenu est cohérent:

# /etc/fstab: static file system information.

Merci

A noter que ce disque "maitre" sda est un SSD de 120 Go, cela peut, peut-être, interférer avec le contrôle. Curieux comme panne : lorsque je lance le disque image corrompu de Precise, cela rétabli la situation (le contrôle de ce disque DVD en live indique des erreurs secteurs) et, ayant pu avoir un bon live-DVD de Precise, la panne de lenteur revient... Grrr. C'est pour çà que je demande de l'aide, car c'est incompréhensible pour mon niveau et j'ignore si une installation de Precise ou Trusty rétablira les choses...?

Alors que dans les deux-trois sessions normales que j'avais hier et ce matin mtab était cohérent avec fstab. Dans l'utilitaire de disque, sda était dans le SSD maitre quand cela fonctionnait normalement, par contre, il indique sdc1 lorsque c'est buggé. Quand j'ai réinstallé Ubuntu pour réparer le réseau, il était demandé d'indiquer une partition d'installation ou sda n'était pas inscrite, mais sdc disponible et je l'ai pris en compte, pensant qu'il ne s'agissait que d'un processus temporaire, il y a donc une confusion entre sda et sdc au démarrage, à priori.

Apparemment, il fonctionne correctement (depuis deux ans), mais cette confusion sda/sdc1 est probablement la cause de cette lenteur. Comment y remèdier, selon ton avis?

Comme je vois que je m'enfonce dans l'erreur, j'ai suivi le tuto pour la commande TRIM pour le SSD, qui est probablement en train de défaillir, sur cette page : http://www.webupd8.org/2013/01/enable-t … rives.html 
mais la vérification:  "sudo fstrim -v /" indique "command not found", voici /etc/cron.daily/trim :

#!/bin/sh
LOG=/var/log/trim.log
echo "*** $(date -R) ***" >> $LOG
fstrim -v / >> $LOG
fstrim -v /home >> $LOG

Andrew, l'auteur, dit d'éditer les partitions, mais où? est-ce que TRIM est mal écrit ou manque-t-il quelque chose?

Non, ce n'était qu'une simulation . Mais en faisant la commande effective, j'ai ce message :

This operation could silently destroy your data.  Are you sure (y/N)? 

Alors avec la dernière ligne, j'hésite.....

Problème matériel : la carte-mère (MSI 990FX)est détériorée ou incompatible avec le kernel : en voulant préparer une clef USB pour les commandes TRIM, les ports USB étaient invisibles sous Lucid. En installant Precise (NB:pas de son), la lenteur a disparu, et tout marchait convenablement, jusqu'à un reboot ou là, les ports USB disparaissent de nouveau, pour réapparaitre après une extinction de la machine de plusieurs jours et redisparaitre lors d'un reboot.
