Which problems, exactly?
Note that recent massive "NCQ horkage" isn't necessary due to drives fault.
Search for "spurious completions during NCQ" for recent discussions
(many of them).

it is spurious completitions and I saw that because of that the drives are
blacklisted. Moreover, the same drive is already blacklisted but with
different firmware.
