Hi Warner, just resurfacing this thread because I've had a few lockups 
on my workstation running 14.0-STABLE.  I was able to capture a photo of 
the hang and this seems to be the most important line:

nvme0: Resetting controller due to a timeout and possible hot unplug.

When I scan the device after reboot I don't see any errors, but if there 
is a particular thing I should check via nvmecontrol please let me know. 
  Also, since it mentions possible hot unplug I wonder if this is 
hardware/firmware related to my system?

Anyway, haven't found a repro case yet but it has locked up a few times 
the past two weeks.
