This is with 2.6.16-rc3, your patch, and running nine Maxtors disks
over onboard nForce4 and MV88SX6081 8-port SATA II PCI-X Controller (rev 09).

for i in `seq 10`
do dd if=/dev/zero of=bigfile.$i bs=1024k count=10000
done
md5sum bigfile.*

The errors mostly seem to happen during the md5sum (not during the dd).

SCSI opcode 0x2a is WRITE_10, so the errors are being reported
in response to the writes to bigfile.$i. But these are different
from the previously reported error status values -- I wonder why
it's getting "Busy" back as a status here ??
