The patchlet below blacklists NCQ on OCZ CORE v2 SSD drive(s). Even though the
drive advertises NCQ support with queue depth 1, it responds with all-zeroes
FIS to NCQ commands which triggers ata error handling several times before the
kernel decides to disable NCQ on the drive.

Please capitalize the leading s and add --- separator between
description and the patch body.
