libata: blacklist NCQ on OCZ CORE 2 SSD (resend)
Browse files Browse the repository at this point in the history
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.
