Erreur kernel avant plantage
Bonjour à tous,
j'ai un serveur sous debian etch qui a planté (ping mais plus
aucun service : ssh, apache ...), j'ai trouvé dans le syslog des
erreurs assez curieuses :

J'ai cherché sur le net les causes de "BUG: unable to handle kernel
paging request at virtual address" mais pas grand chose sur debian ou
alors en rapport avec des périphériques ou drivers que je n'utilise
pas.
Quelqu'un pourrait m'aider à déchiffrer ça ?
merci à tous,
bonne journée,
Benjamin SCHILZ
