Hello!

We have an amd64 machine with an nVidia3 SATA controller on motherboard.

The drive just came from the manufacturer and the self-tests initiated
via smartctl show no problems:

atapci1: <nVidia nForce3 Pro SATA150 controller> port 0xcc00-0xcc07,0xc800-0xc803,0xc400-0xc407,0xc000-0xc003,0xbc00-0xbc0f,0xb800-0xb87f irq 22 at device 10.0 
on pci0
ata2: <ATA channel 0> on atapci1
ata3: <ATA channel 1> on atapci1
ad6: 238475MB <WDC WD2500SD-01KCC0 08.02D08> at ata3-master SATA150


Yet even newfs-ing it leads to DMA errors and the drive is unusable:

% newfs -f 8192 -b 65536 /dev/ad6
/dev/ad6: 238475.2MB (488397168 sectors) block size 65536, fragment size 8192
        using 81 cylinder groups of 2969.06MB, 47505 blks, 95232 inodes.

After each such attempt, the kernel complains loudly:
[...]
ad6: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=249306496
ad6: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=261467776

ad6: FAILURE - WRITE_DMA48 status=51<READY,DSC,ERROR> error=10<NID_NOT_FOUND> LBA=273629312

Is this controller working for others? We connected the disk to it in
preference to the Silicon Image connectors, which are also present
on-board, because SI has poor reputation :-(

Is this controller supposed to work? Thanks!
