Errors are very consistent. Data transfer from the host to the drive
fails and SError indicates Handshake Error, Non-recovered transient data
integrity error and often Recovered Data integrity error. For some
reason, your drive doesn't like what it's hearing from the controller
and replies with R_ERR.

As error reporting when using ata_piix is very limited. It gets
reported as host bus error but I think it's basically the same problem.
I don't think this is driver issue. I have the same controller and I've
never seen similar thing happening and I have plenty of drives and test
them often. Error reports also point to transmission problems. Your
drive just doesn't like what it's hearing. Does 'smartctl -a /dev/sda'
tell anything special?
