This problem has been there a long time, at least since 3.0. It does not only affect the CS20/DS20L but also the DS20 and 264DP. It is also the reason why I gave up on trying to use NetBSD on my production boxes. I suspect it might be related in some way to the problem Michael described too as I ran in to that problem when I tried to boot my boxes with a non-MP kernel. I didn't dig deeper into the cause however I can say that it is not driver specific, the same problem occurs regardless of if your disk is hooked up to the internal SCSI chain or to a card in the PCI slots. It doesn't seem to be SCSI specific either as for me it thrashed the filesystem on disks hooked up to the ATA controller too when I tried that.
Cheers,
Anders
