Could this be the DMA across page boundaries bug? I'm guessing that these
files weren't corrupted on transfer, because tcp checksums would have
cought that. Could it be the IDE drive using DMA that's causing the
problems? The IDE controller is on the first PCI bus, so it hasn't gone
across the ppb. If this is the case would a scsi controler fix it? I
notice that all of the people who have reported sucess with the miatas
have had scsi. This still doesn't explain why it would work in
FreeBSD/Linux/NT and not netbsd though. There must be some software
glitch at play here along with the bunk hardware.
