"panic occurred, switching back to text console"
Bonjour,
Depuis environ un mois, mon ordi plante tous les jours systématiquement au premier démarrage, parfois après 20 secondes, d'autres fois après 10 minutes. En général on a le temps de lancer firefox et après ça plante, mais pas toujours, des fois il plante avant. (au deuxième démarrage, en général tout va bien) L'écran devient tout noir, et à partir de là les messages d'erreurs varient. Impossible de copier quoi que ce soit. Parfois ALT+SYST+S puis E, I, U, B nous donne quelque chose mais plus souvent rien du tout.
Mais revient souvent (d'où le titre de ma discussion) :
panic occurred, switching back to text consoleOn a aussi du :
kernel panic - not syncing : fatal exception in interruptDes fois il ne va même pas jusqu'au GRUB et ne fait rien du tout, juste écran noir et curseur.
Je travaille sur un "vieux" laptop Nec de 2007 (ça me parait pas si vieux que ça...), avec Ubuntu 12.04 (32 bits), Noyau Linux 3.13.0-34 et Gnome 3.4.2.
Ma racine est à 25%, mon home à 83%. On a eu un dual boot il y a longtemps, mais maintenant on n'a que Linux.
Voilà. Je me demande surtout à quoi c'est dû, si c'est un problème matériel ou autre... Et si c'est un problème matériel, est-ce que je peux faire quelque chose sans racheter un ordi ??
Merci de vos conseils 
PS : j'ajoute des infos sur ma config après avoir vu un fil de discussion similaire :
