Warning the dma on your hard drive is turned

Salut,

Peut être que l'article de la base de connaissances t'apportera quelques éclaircissements : http://www.commentcamarche.net/faq/sujet-812

Salut jipicy,

en fait tu m'as mal compris.
Je voudrais simplement activer mon dma mais hdparm -d1 /dev/hda me renvoit ce message d'erreure:

HDIO_SET_DMA failed: Operation not permitted

J'ai fait des recherches sur le net mais tout ce que j'ai éssayé jusque là n'a rien donné.

Re-

Peux-tu afficher le fichier de conf de ton bootloader (/etc/lilo.conf si je ne m'abuse sous Slackware).
Et tant qu'on y est les 1ères lignes de "dmesg" (disons les 30 premières).
Merci

Ben désolé mais j'ai pas trouvé ce que j'espérai trouver dans l'affichage (je cherchais une ligne du genre "ide=nodma" qui m'aurait bien arrangé ;-)) )

Bon reste un truc à voir : le DMA est-il activé dans le noyau ?
Essaie de regarder dans le fichier de conf du noyau qui doit se trouver dans "/boot" normalement...
