Warner,
Is it going to be possible to MFC the NCQ trim fixes, or is this
dependent on post 10.x work?
It took a longgggg time for Linux to catch up with Crucial's firmware

cheers
Bruce
[1] Which, by the way, is an excellent example of vendors doing the
right thing for a change, as the patch was delivered as a Linux-based
self-booting image (ISO/USB/etc).
