At least tangentially related:

On one of my boxes (running 2.6.18-1.2869 from Fedora) I have a
couple of other Maxtor drives that didn't like NCQ. They are on a
JMicron 20360/20363 (ahci driver). (There's also a Promise 300 TX4
card in the box and an Intel ICH8 that shows up with ata_piix).

model and (partial) firmware revision of the drives:
Maxtor 7V300F0 VA11
Maxtor 7B300S0 BANC

Until I disabled NCQ I got gazillions of messages like the ones below
and absymal performance.
