Make sure you have BLK_DEV_NVME compiled into your kernel (not as a
module), and that you pass the right device name as a root FS to the
kernel. It might also help to use a very recent kernel.
FWIW, I'm writing this from a laptop that boots from two NVMe devices in
RAID 1 configuration, with kernel 4.4.5.
