Freeze avec un SSD qui cessent quand il passe en 3 Gb/s

fanum

Discussion déplacée suite à une investigation plus poussée (initialement ici).

Bonjour,
Depuis une double évolution (changement de CM+CPU+Ram+Gpu) et mise à niveau de 16.04 à 18.04, je sais, ce n'est pas malin d'avoir fait les deux en même temps et une installation propre aurait été plus intelligente), j'ai des l'allumage du PC des freeze de plusieurs secondes à une minute. D'après dmesg, ces freeze se terminent par un «link up» du SSD en 6 Gbs et recommencent. Puis au bout d'une dizaine de freeze, le SSD est «link up» en 3 Gbs et du coup il n'y a plus de problèmes, toute la session se passe bien.

Est-ce un problème de SSD en fin de vie, une incompatibilité avec la CM et avec 18.04 ??

Voici ma configuration :
- Ubuntu Mate 18.04.1 64 b
- noyau 4.15.0-33
- Intel i5 8500, DDR4 8 Go sur carte mère Gigabyte B360M D3H
- carte graphique NVidia 1050 Ti 4 Go avec le pilote nvidia 390.48 mais le problème se produit aussi avec le pilote nouveau et également quand je démarre sur le GPU Intel

La fin du dmesg du jour :

Et vous trouverez sur l'autre discussion le smartctl du SSD.

Merci d'avance pour votre aide

Modération : la prochaine fois signale ta discussion en demandant à la modération de la déplacer là où tu le souhaites.

fanum

Mes excuses à la modération pour n'avoir pas prévenu du déplacement.

Bonjour

Deux autres tests
1) Vérifier que le bios de la carte mère est bien positionné sur AHCI et non sur IDE.
2) Débrancher tous les autres disques et vérifier si cela fonctionne avec le seul SSD (manque de puissance électrique?)

Il est possible que bionic ait modifié le code de NCQ que le SSD ne comprend plus.
1) Modifier un paramètre du fichier /etc/default/grub pour qu'il devienne

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash ro libata.force=noncq”

Je pense qu'on devrait pouvoir dire "pour seulement ata5" mais je ne trouve pas réellement confirmation

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash ro libata.force=5.0:noncq”

2) mettre à jour le grub

sudo update-grub

fanum

Merci pour ton message.

Je vais voir pour le bios (si je trouve) et pour l'alim. En attendant, j'ai rebooté et voici le dmesg | grep NCQ

[    3.998819] ata3.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 31/32), AA
[    3.998938] ata4.00: 3907029168 sectors, multi 16: LBA48 NCQ (depth 31/32), AA
[    4.016865] ata5.00: 117231408 sectors, multi 16: LBA48 NCQ (depth 31/32), AA

Il n'y a plus NCQ disabled et pourtant je n'ai pas de freeze. Par contre, le SSD est toujours en Gbs. Si je reboot, il reste en 3 Gbs alors que si j'éteins et rallume, il repasse en 6 Gbs et ça freeze jusqu'à ce qu'il repasse en 3 Gbs. Le problème semble plutôt venir de là que de NCQ. Je vais ouvrir la tour et tester sans HDD.

PPdM

peut etre un souci de pilote
essayes ceci

sudo apt update && sudo apt dist-upgrade -y

pour estre sur qu tout est a jour

fanum

Les mises à jour n'ont rien apporté.
Le bios est bien en AHCI mais je n'ai pas réussi à démarrer sans les deux HDD (j'avais le logo Ubuntu, en faisant F11 j'ai vu qu'il essayait de trouver les HDD mais ça n'ouvrait pas de session). Faut-il enlever les HDD du fstab pour pouvoir démarrer sans ?

PPdM

Ton grub est sans doute installé sur l'un des autres disques ce qui explique peut etre tes problèmes*

Tu peux essayer de redemarer , avec juste le ssd, sur un cd d'installation et de réinstaller ton grub sur le bon disque

fanum

A priori non car j'ai bien eu grub, c'est ensuite quand le logo avec les petits points est apparu que ça a tourné en rond pendant longtemps avant de me donner la main en console uniquement.

Bonjour,
Mon problème a été résolu par une installation propre de bionic. C'était bien un problème suite à la mise à niveau de 16.04 à 18.04. Merci à ceux qui m'ont aidé.
