Do we have information that these drives fail on non-SiI controllers?

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.

- ask

ata5: spurious interrupt (irq_stat 0x8 active_tag -84148995 sactive 0xf)

Sounds like those are some that we should be blacklisting as well, unless Eric has a good reason why not (CCing). Can you provide the full firmware revision strings from those drives, i.e. from "hdparm -I"?
