puhh - just guessing ... I have enabled
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y
you have chosen the correct driver for your chipset and you're loading it at startup ? (forcedeth) |

| forcedeth is a network driver, not a DMA driver. You already have the correct driver enabled and built in ot the kernel, personally I would also set "Use PCI DMA by default when available" to see if that helps. |

No, still nothing.
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off) |
