https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211713 --- Comment #33 from Terry Kennedy <terry-freebsd@glaver.org> --- (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=3D1" traces that he requested. He had me configu= re the driver with "hw.nvme.per_cpu_io_queues=3D0" 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
