--- Comment #42 from Colin Percival <cperciva@FreeBSD.org> ---
Can you try setting hw.nvme.timeout_period in /boot/loader.conf?  In
particular:

1. Setting it to "1" may result in more errors being logged but less hanging,
and
2. Setting it to "3600" (or something similarly big) may result in fewer errors
but longer hangs.

I don't think either of these is a solution but it would be very enlightening
to know if either of these has the anticipated effect.
