No, i did not manage to improve (it should NOT be a dangerous error BTW).

I simply think that this issue is because of buggy firmware, so i

posted to linux-ide a patch to blacklist this hard disk from using NCQ

(because it is triggering spurious completions).

I don't know what the "blacklisting policy" is for linux kernel

developers, i think that, since there probably are a lot of buggy

drives for NCQ and so, a module parameter to disable NCQ while loading

libata could be useful.

Best regards.
