The 3 IDs should match I believe and the firmware parameter is NULL.
Affected firmware versions include at least the latest 1916 and the
previous 1819, likely older ones as well.

Tested with my own Crucial CT128M225 model which has the IndiLinx
Barefoot controller.

The libata-core.c file has an existing line for "OCZ_CORESSD" for a
particular firmware version
but I suspect many, if not all of those controllers may have this issue?
At least one user of Intel SSDs reports no issues with existing
kernels and I've read that
they do NCQ right.
