http://imgur.com/a/CkeRj using genkernel on a new install on my laptop(lenovo X1 yoga). any ideas why the UUID root partition is not being found? I verified with blkid that the partitions UUID are correct with the live usb.

It looks like the SATA driver is good. Trying to avoid any manual compilation of the kernel by using genkernel. The 2016 Gentoo Live usb had no issues.

Can you post a copy of /etc/fstab, the output from blkid, and your /boot/grub/grub.cfg file?

I'm using a USB stick made from the latest minimal CD iso (7/20/2017). Only takes a few minutes to update it.

I tend to get this message when I mess up either partitioning or mounting stuff during installation so kernel can't find init afterwards.

Easy to check: initramfs already suggested you typing "shell" instead of the block device so you can have a look around and find out what's up.
Fstab is not relevant this early during boot, but mounting partitions and checking their contents can help you sort it out.

when you get to the prompt shown in your photo post, try PARTUUID=<whatever blkid reported> or /dev/sd<guess kernel block device names> you can edit the kernel options your bootloader menu has to match whatever worked

Found the issue.... for whatever reason, GRUB2 will not work when you use UUID on NVME. I used the device NVME name instead(/dev/nvme01np6) and it worked great. This is not a issue with fstab(UUID works fine), only in GRUB2.
