Yes, indeed.  That's a very good reason not to recommend the newest and
shiniest.  I haven't seen any problems so far, but then again it's only
been a day or so and we haven't got into the full testing regime quite
yet.  I'll let you know if we do run into problems.

Is there work on hot-plug NVMe going on?  ISTR jmg@ mentioning hotplug
PCI at the dev summit at Stockholm EuroBSDCon, but not much since then.

	Cheers,
