There's been a long and elaborate discussion of this issue, and even some investigations ;-) Consensus seems to be that there is a hardware/timing issue on some(?) chipsets, possibly related to DMA operation. I could reproduce it on Supermicro SATA machines and no-name (Aquarius) with Adaptec SCSI, but it never happend on Dells with Megaraid.
