Remy (and others),

I have been trying to get Gentoo to boot from an NVME device, but I am getting 
stuck.

The kernel-config I use will boot when the root-device is on a spinning sata-
disk and I can see the NVME device.
When using the same config with the root-partition on the NVME, it fails, 
complaining it can't find the root-partition.

The NVME driver is loaded into the kernel (not module).

Does anyone have a working config for a 4.4.6 kernel or any other version that 
is currently in portage?

Along with the boot-options being used?

Many thanks,

Joost
