--- Comment #51 from Alexander Motin <mav@FreeBSD.org> ---
(In reply to Daniel Austin from comment #48)
I see mpsutil/mprutil tools recently got support for `set ncq` subcommand, =
that
should allow to disable NCQ.  I've merged that into TrueNAS 12.0-U7.  I hav=
en't
tried that myself, and it makes me shiver inside from its inefficiency, but=
 I
can believe that it may reduce maximum command latency in some scenarios, or
may be even avoid command timeouts in situations when the disks or the HBAs
can't schedule or process the NCQ commands reasonably.
