Suite au fil dans pause café je vais décrire mon problème principal ici.
Je branche ma clé usb, j’ai les lignes suivantes dans kern.log

Je copie un répertoire contenant plein de fichiers de 5Mo environ, la copie commence à un débit digne de l’usb2. Au bout de quelques secondes le débit tombe à 100ko environ.

J’ai évacué l’idée d’un problème matériel quand j’ai vu que tout tournait impec avec un noyau 2.6.18.
EDIT : Quand j’en suis là, ce n’est plus la peine de chercher à brancher quoi que ce soit même une souris.
