salut,
N’ayant plus d’idée (et google non plus) pour résoudre mon pb, je vous poste celui ci.
Le probleme à resoudre et l’activation de l’Ultra DMA.
J’ai une debian (sid) avec un kernel 2.4.21 compilé maison.
Je precise que je n’ai jamais reussi a faire fontionner UDMA sous linux depuis que j’ai cette machine au boulot.
hdparm:
hdparm -d 1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
et pourtant:
hdparm -I /dev/hda
/dev/hda:
