From a message posted to the FreeBSD stable mailing list:
Folks who use SATA (speaking generally here because there's too much
that got touched) should be aware:
Within the past ~7 hours there have been a *very* large number of
commits by mav@ that pertain to SATA-related storage controllers and
I would advocate that folks rebuild world/kernel and make sure there
aren't any issues seen, or any quirks which were previously needed are
I haven't gone through *all* of the commits yet, but I do see some
controller-centric things that got MFC'd, such as disabling of NCQ
support on multiport Marvell 88SX61XX to relieve I/O timeouts when
doing lots of I/O (common with ZFS).
Below are the commits. Users should absolutely use cvsweb or similar
tools to examine the commit message and see if anything relevant to
their storage subsystems was modified.
For the list of commits (omitted here), refer to the original message
