Par kernel_task je suppose que tu veux dire Kernel Panic (c'est-à-dire : l'ordinateur plante et indique en plusieurs langues qu'il faut redémarrer) ?
Si c'est bien le cas, un rapport d'erreur est sans doute créé au moment de ce KP (raccourci pour Kernel Panic). Il faudrait que tu nous l'affiches (en entier si tu ne sais quelle partie choisir).
Pour ce faire, ouvrir l'utilitaire Console et regarder dans les rapports systèmes (si je me souviens bien).
Bonjour à vous, @Bompi
Voici le rapport système copié de la console.
(Bonne lecture)
