    [Slackware]Errore dma al boot

    Ciao ha tutti, da quando ho ricompilato il kernel 2.6 al boot mi compariva il messaggio
    "warning the dma on your hard drive is turned off "
    ho ricompilato includendo il chipset per la mia scheda madre (VIA) e adesso l'errore non si presenta più ma non sono sicuro che vada tutto a buon fine sembra che il dma dia ancora degli errori.
    Questa è la sequenza di boot (verso la fine):
    codice:

    il boot va comunque a buon fine e slackware 10.1 si avvia senza problemi.
    in questo modo il dma è attivo oppure no? grazie per l'aiuto

    Lo verifichi con:

    hdparm /dev/hda2

    se e' attivo appare:

    using_dma = 1 (on)
