Bonjour. 
 
Mon portable du boulot est un Toshiba L40. Il tourne en double boot XP Ubuntu. 
J'ai suivi ce tutoriel [http://doc.ubuntu-fr.org/atheros_ar5007eg](http://doc.ubuntu-fr.org/atheros_ar5007eg) et le wifi fonctionne. Cependant, au bout d'un certain temps d'inactivité, j'ai un joli crash, écran noir avec une série de messages que je retrouve dans le kern.log

Ça fait penser à un problème avec le WiFi mais le moment du plantage fait aussi penser à l'économiseur d'écran ou aux fonctions de mise en veille. 
 
J'en suis là, n'ai rien trouvé d'exploitable via internet et vous serait reconnaissant d'un coup de main ou d'une piste qui m'aurait échappé.
