J'ai installé Ubuntu 14.04, et j'obtiens un système de fichiers en lecture seule (/dev/sda3) de manière aléatoire. Auparavant, j'utilisais Arch linux (3.14 lts), qui avait le même problème mais que j'ai abandonné à cause d'autres problèmes. J'ai testé la partition avec badblocks (read only test) mais je n'ai pas eu d'erreur. Voici la sortie dmesg après avoir obtenu l'erreur
