Dear gentoo folks :
I am making very very slow progress with the SiFive P550 RISC-V

That specifically shouldn't be the problem, given that the output shows
the bootloader loading that ramdisk as well as output from what ought to
be the in-ramdisk system itself (notably "Dropping to debug shell."
above)?
Yes, you are quite right. 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.
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.
