--- Comment #41 from Martin Stafford <martin at humeco.com> ---
Same problem here.
Works fine under Debian Stretch 9.2 with same hardware.

Supermicro X10DRL-I-O motherboard
ASUS Hyper M.2 x16 NVMe card
2 X Samsung PM961 256gb
1 X Samsung PM961 128gb

I've disabled the hw.nvme.per_cpu_io_queues and it's working but slow I think.

Here's some dmesg lines with hw.nvme.per_cpu_io_queues=0:
