J'ai remarqué que quelque chose bloque bien le démarrage pendant 10s (3 -> 13s)
De ce que je comprend le problème est en rapport avec un port USB, j'ai essayé de tout débrancher, mais toujours pareil.

Pour info la machine est un laptop MSI 660R


Une idée ? :copain:

Salut, sur quelle ligne le démarrage reste-t-il bloqué ? Ce sera peut-être plus parlant qu'un dmesg partiel ?

Dans le dmesg ça correspond à c'est ces lignes la:
Si les chiffres à gauche sont bien les secondes il bloque 10s avant de déclarer un timeout, mais je n'arrive pas à comprendre sur quoi :s

Salut,

En ce cas, juste après la fin du boot, sors un dmesg complet mais mets-le sur pastebin et donnes le lien.

Il faudrait rechercher pourquoi ça bloque sur cet usb : as-tu un hub externe branché sur la machine, par exemple ?
(cela dit, 10 secondes d'attente supplémentaire ne me semble pas catastrophique... )

Voila le dmesg complet
L'attente se fait à la ligne 799
http://pastebin.com/kwe9qBMy

C'est sure, 10s c'est pas la mort, mais c'est rageant de perdre le tiers du temps de boot sur un timeout :p

J'ai pas de hub non. Lors de ce boot j'avais une souris et un nexus One branché en usb. Mais ils ne sont pas en cause, car même débranchant tout les periph externes du PC ça bloque aussi.
J'ai essayé de regardé un peu, j'ai trouvé une reférence vers un manager de led (Décorations sur le laptop, j'ai des lupiotes qui clignotent :D) qui sous Windows fonctionne.
Peut être qu'en désactivant ce système je n'aurai plus ce problème, mais j'ai pas trouvé de moyen de désactiver 1 seul port USB

Dans la partie USB du BIOS j'ai:
- Legacy USB support
- EHCI Hand-off
- Device Reset timeout

J'ai désactivé les 2 premiers et diminué le timeout du 3ème mais rien ne change :'(

Merci de ton aide en tous cas :)
