DennisYou have reached to the trully nightmare of embeeded devices. How the hell can I boot this shoe box, I spent nearly 4 months in make rockpi boot.
Have you thought in specify the rootfs by device instead by uuid? as in root=/dev/mmcblk0p3. If it works the trouble is that someone has not UUID support.

I was thinking if Dennis is going to check through his installation he might as well check GRUB borrowed from Ubuntu too.The GRUB situation is very strange. p550# p550# mount /dev/mmcblk0p3 /mnt/gentoo I did the emerge twice inside the chroot stage3 : p550# p550# grep -n 'completed' /mnt/gentoo/var/log/emerge.log | grep -i 'grub' 561:1753295980: ::: completed emerge (5 of 5) sys-boot/grub-2.12-r7 to / 610:1753297404: ::: completed emerge (6 of 6) sys-boot/grub-2.12-r7 to / p550# That results in a GRUB binary that is very different from the thing I stole from the SiFive Ubuntu flash stuff : p550# p550# ls -l /opt/gentoo_efi/EFI/gentoo/grubriscv64.efi -rwxr-xr-x 1 root root 159744 Jul 23 19:07 /opt/gentoo_efi/EFI/gentoo/grubriscv64.efi p550# p550# ls -l /mnt/mmc_efi/EFI/ubuntu/grubriscv64.efi -rwxr-xr-x 1 root root 3608576 Jul 16 13:06 /mnt/mmc_efi/EFI/ubuntu/grubriscv64.efi p550# Very different sizes there. The Ubuntu stuff is from 16th of July and seems to be at least twice as large. Could be more modules. No idea really.Is there a reason you have borrowed the Ubuntu GRUB executable? I wouldn't min 'n match bootloader images. If you must try them both, try them one at a time.The GRUB that I built inside the stage3 chroot has never seen the light of day yet. It exists but I have not used it. It may be a better way to go here. For the moment just getting past this strange dracut UUID mixup seems reasonable.I suggest in the first instance you mount *all* necessary partitions and then follow the gentoo handbook to chroot into it. Once you are in the chroot'ed system you check GRUB_PLATFORMS="..." is set correctly for your platform's architecture, re-install GRUB, run 'dracut', before you finally run 'grub- mkconfig -o /boot/grub/grub.cfg' to generate GRUB's configuration. Exit, unmount and reboot to see what you get.
