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
