[mise en veille] plantages aléatoires

[vintherine]

J'utilise souvent la mise en veille (en mémoire, pas l'hibernation). Généralement ça se passe bien mais pas toujours : il arrive parfois que la machine ne réagisse plus, que le ventilateur continue à tourner, et qu'il ne me reste plus que le big red button comme solution pour redémarrer. Je ne trouve rien de particulier dans les logs.

Quelqu'un aurait-il une idée ? Si oui merci d'avance

extrait de /var/log/messages.log lors du dernier plantage:
