Forum Linux.noyau Problème avec cpufreq sur un portable

Bonjour,

Je viens d'installer Mandrake 10.2 sur un portable AMD 64 3700+.
Le module cpufreq se charge et fonctionne apparemment correctement, mais il ne se décharge pas, et empêche l'arrêt de la machine.

J'utilise le noyau 2.6.11-6.
Le problème est le même avec la version 32 bits et 64 bits.
J'ai posté une partie de /var/log/messages ci dessous.

Merci pour vos idées !

Olivier V
