Subject: Why I couldn't turn the DMA mode on ?
Date: Thu, 19 Jun 2003 20:56:53 -0700 [thread overview]
Message-ID: <00bc01c336df$fdfa92d0$6b01a8c0@bmoon> (raw)

I rebuilt kernel with 2.4.20 with patch ,
then I can not set the DMA mode on my
hda drive.
> hdparm -d 1 /dev/hda
/dev/hda:
setting using_dma to 1(on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
I have no problem with old REDHAT7.1.
From my .config,
CONFIG_BLK_DEV_IDEDMA_PCI = y
# CONFIG_BLK_DEV_IDEDMA_FORCED
CONFIG_IDEDMA_PCI_AUTO = y
CONFIG_BLK_IDEDMA = y
Any comment or suggestion?
