VP_IDE: VIA vt82c596b IDE UMDA66 controller on pci0:7.1

Actually I get other stuff than SeekError:

hda: irq timeout: status=0x58 { DriveReady, SeekComplete, DataRequest }
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: DMA disabled

(same for hdc)

According to the output I get, I have vt82c596b. Are you sure?

I've tried to boot it without ide0=ata66 and got the same result.
I've been running the system with ide0=ata66 without any problems.
Plus, I have this in the boot script:

/sbin/hdparm -c 1 -m 16 -d -X66 /dev/hda
/sbin/hdparm -S 50 /dev/hda
/sbin/hdparm -c 1 -m 16 -d -X66 /dev/hdc

I haven't seen any problems and I'm getting a nice 20MB/sec on /dev/hdc.
