problemi abilitazione DMA
se cerco di abilitare il dma, ottengo il seguente errore:
#hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
---------
ricercando ho visto che quasi sempre questo errore dipendeva dal
mancato caricamento di moduli adatti per il chipset.
ho cercato di capire quale sia ilmodulo del kernel da caricare.
ho un pc ibm thinkcentre 8189, con scheda madre e chipset intel.
sicuramente un modulo per chipset intel.
ma non sono andato oltre...
qualche suggerimento? :-)
di seguito allego l'output di lspci e lsmod
ciao e grazie
Max
