--- Comment #1 from Thierry Thomas <thierry@FreeBSD.org> ---
I have tried many things: BIOS tweaking, with or without
hw.nvme.use_nvd, with vmd_load, etc., but no satisfying result ATM.

Note: initially, a device /dev/ntfs was shown and locked one NVMe. It was
caused by KDE, and freed when I booted the machine without starting KDE.

This is very strange: at some time /dev/nvd0 and /dev/nvd1 were there,
nvmecontrol identify was OK for the two devices, gpart destroy of the
Windows stuff, gpart create and gpart add -t freebsd-zfs were
successfull, and I created two zpools on them.

But they are not persistent! After a reboot, I see sometimes only one of
them, and sometimes noneā€¦

Remark 1: when I can see a zpool, this is always the same. And yes, when
the machine ran Windows, both SSDs were always active.

Remark 2: it seems that chances to get at least one NVMe are greater after a
cold boot, and chances to see none of them are greater after a reboot.
