[PATCH] libata: add NCQ blacklist entries from Silicon Image Windows driver (v2)
This adds some NCQ blacklist entries taken from the Silicon Image 3124/3132 Windows driver .inf files. There are some confirming reports of problems with these drives under Linux (for example http://lkml.org/lkml/2007/3/4/178) so let's disable NCQ on these drives. [ I'm personally starting to wonder whether we shouldn't disable NCQ by default, and perhaps have a white-list. There seems to be a *lot* of drives that do this wrong.. - Linus ] Signed-off-by: Robert Hancock <hancockr@shaw.ca> Acked-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
