kg7-RAID: DMA timeout error

I have attached a new hdd to my integrated raid controller, but i have the following message from the kernel:
HPT370A: IDE controller at PCI slot 0000:00:13.0
HPT370A: chipset revision 4
HPT37X: using 33MHz PCI clock
HPT370A: 100% native mode on irq 11

The hdd is unusable slow under linux, but it works fine with win2000. I googled for a solution a lot, but i found nothing.

I use 2.6.1 kernel and Debian unstable.
Here is some important part of my kernel's conf:
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_ADMA=y
CONFIG_BLK_DEV_HPT366=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y
