Salut.
J’ai ce probleme sur l’un des ordinateurs de la maison, a chaque fois que je tente d’utiliser le lecteur de CD, le systeme freeze. Quand je tente de redemarrer X, ce message apparait jusqu’a ce que ca freeze completement :
J’ai tente de regarder certaines infos pour voir ce qui peut poser probleme, mais je ne comprends pas grand chose, si ca peut vous aider a me mettre sur la voie :

Quant a # cat /var/log/messages | grep hdb ca donne beaucoup de choses. Quelques extraits :

Le probleme etant que comme je dois redemarrer a la brutale apres le freeze, je ne sais pas si ces messages sont utiles, puisqu’apres reboot.
Voila, ca fonctionnait bien sous Ubuntu avant, donc je ne pense pas que le lecteur soit defectueux.
Merci de m’eclairer sur ce probleme.
