Yea, so far this is the only report I've received, and there's not 
enough data in it to reproduce it with any of the dozen NVMe drives that 
I have, or to spot a difference with what I know I check in the code. So 
if it's compiled into the kernel with cam also compiled into the kernel, 
I know it works.

CAM is in the kerne, nvme is loaded as a module (from 15-current):
---snip---
# kldstat | egrep '(nvm|cam)'
  2    1 0xffffffff811e3000    20db8 nvme.ko
---snip---

I will do a clean rebuild with the most recent 16-current and provide a 
full dmesg if this still doesn't work.

As a module it fails:
[1] link_elf_obj: symbol nvme_handle_aen_desc undefined
[1] KLD file nvme.ko - could not finalize loading

Bye,
Alexander.
