Comment:
I was seeing timeouts but they seem to have gone away. I think it's a
question of the hdparm settings being poorly configured

these settings in /etc/hdparm.conf works fine for me

command_line {
        hdparm -q -d1 -q -X udma5 -q -c3 -q -m 16 -q -W1 /dev/hda
}

Maybe it's an issue without multiple sector io enabled (hdparm -m 16)
