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.
