Hi,

sorry for late response. Now the results in smart mode:
---------------------------------------------------
IT8212: IDE controller at PCI slot 0000:00:09.0
ACPI: PCI Interrupt 0000:00:09.0[A] -> GSI 17 (level, low) -> IRQ 18
IT8212: chipset revision 17
it821x: controller in smart mode.
IT8212: 100% native mode on irq 18
ide2: BM-DMA at 0xdc00-0xdc07, BIOS settings: hde:pio, hdf:pio

------------------------------------------------------

# hdparm -d1 /dev/hde

/dev/hde:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Input/output error
using_dma = 0 (off)

-------------------------------------------------------

Buffered reads: 3.06MB/s

Seems I shot too quick, DMA in smart mode still does not work.
"noraid=1" also works without the patch, correct.

Best,
Tom
