Debian stretch lent au démarrage avecmessages d'erreurs

Support Debian
#1

Bonjour,
j’ai réinstallé tout proprement debian 9 sur mon ordi (lenovo Z50)
Au démarrage, il est vraiment très lent et j’ai tout un tas de messages d’erreur.

la commande dmesg -l err me donne

la wifi galérait mais après un petit recovery mode, ça s’est mis à fonctionner, par contre pas de bluetooth…
merci d’avance pour votre aide!

#2

Des messages mentionnent des firmwares ethernet, wifi et/ou bluetooth manquants qui pourraient être inclus dans le paquet firmware-realtek de la section non-free.

#3

Bonjour,
merci pour votre réponse
Entre temps, j’ai installé le paquet firmware-realteck et le démarrage se passe beaucoup mieux.
Il subsiste des messages d’erreurs et il me semble que le bluetooth ne marche toujours pas…

#4

J’ai l’impression que tu as quelques soucis avec ton matériel. Ça sent un petit problème de disque dur.
Essaie d’installer le parquet smartmontools et de nous donner le retour de la commande smartctl -a /dev/sda.

#5

En supposant que sd 4:0:0:0 correspond à sda, ce qu’il faudrait vérifier avec

ls -l /dev/disk/by-path/*scsi-4:0:0:0

Il y a aussi des erreurs ACPI et avec le pilote nouveau du GPU Nvidia.

Concernant le bluetooth, le firmware manquant n’est pas inclus dans le paquet firmware-realtek. Néanmoins il arrive qu’un firmware soit facultatif.

#6

Je pense que les erreurs de nouveau peuvent faire planter le bureau graphique, mais pas ralentir son démarrage.
Quant aux erreurs ACPI, leur présence ne m’a même pas choqué, elles sont probablement très graves ou absolument bénines, je ne saurais même pas dire…
