It looks like this issue has moved over to 2.4-ac now. I too am able to reproduce this on two drives in PIO mode. There are only two drives, hda and hdc. I was copying from hda to md0 (one half of a new RAID1 array that will (completed now as of this writing) be on hda and hdc. I can provide more information upon request.
