I did see an error about not finding /dev/sdb8 - I think that's the problem.
There's a GRUB related bug where for some reason in certain instances
root=/dev/ is used instead of root=UUID=<uuid> and I'm spacing out why
this happens. But the usual fix is to get it to boot manually somehow,
and then recreate the grub.cfg from scratch with grub2-mkconfig - and
invariably that one will have all entries using UUID rather than
/dev/
