ata: NCQ is broken on Maxtor 6L250S0

With this applied, my machine has stopped all those painful messages.
dmesg now says :

root@riri:/Kernels# dmesg | grep LBA
ata1.00: 490234752 sectors, multi 0: LBA48 NCQ (not used)
ata2.00: 640 sectors, multi 1: LBA
ata3.00: 490234752 sectors, multi 0: LBA48 NCQ (not used)
