I don't know if this is the problem, but there was some ata driver
breakage (seems to me tagged queueing might have had something to
do with it, or maybe it was RAID-related) in 4.6-RELEASE.  The
release notes should say something about it.

Meanwhile, you might try reinstalling 4.5-RELEASE, then cvsupping
to 4.6-STABLE to see if that works.
