ad10: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=11441599

My box is a FreeBSD 6.0-BETA2 driven ASUS A8N-SLI Deluxe based AMD64 
boxed (see dmesg).
One of  my SATA disks, the SAMSUNG SP2004C seems to show errors during 
operation (and also showd under 5.4-RELEASE-p3).
Sometimes I get this error:
ad10: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=11441599
while the machine still keeps working.
Other days the box crashes completely.

Is this a operating system bug or is this message an evidence of 
defective hardware?

By the way, DMA support is enabled:
hw.ata.ata_dma: 1
hw.ata.atapi_dma: 1

Thanks in advance,\
