(In reply to Warner Losh from comment #32)

Back when I first ran into this, I sent Jim Harris a bunch of "sysctl
dev.nvme.0.ioq*.dump_debug=1" traces that he requested. He had me configure the
driver with "hw.nvme.per_cpu_io_queues=0" which caused the card to work, but
also crippled performance.

I recently obtained an Optane 16GB NVMe stick, and that one does work in the
Supermicro board (where the PM961 didn't). I don't know if that proves
anything.
