Bonsoir les Linuxiens.
Je viens de me mettre une debian etch (maintenant Lenny) il y a quelques jours. Après moultes domptages de la bête, j’en arrive à vouloir réduire le temps de démarrage.
J’ai donc installé Bootchart pour voir ce qu’il se passe pendant le boot.
Il en sort un graphique vraiment différents des exemples que j’avais vu.
En gros, il se passe 125s avant qu’init et bootchart se lance, ce qui explique le fait que je trouvais le boot assez long 
Voila pour les faits, passons aux preuves !!! 
Alors, pendant le boot, arrivé aux scans des disques dur (hda dans mon cas), ca freeze et me sort plein d’erreurs de “dma timeout error”.
Après de nombreuses recherches (notamment ici avec le topic “scan hdd au boot”),
voilà le fstab:
[code]# /etc/fstab: static file system information.
