This is probably fixed w/ the kconfig updates added 8 days ago [1], can you try a newer iso [2]?

also if you want to try little-endian/ppc64le (which is recommended for blackbird) you can try experimental installcd I'm working on.

iso file can be obtained here:

https://dev.gentoo.org/~gyakovlev/power/

it supports both 64K page kernels and 4K page kernels.
it will be officially released soon-ish, but it already works fine. just need to fix couple minor issues and add trim kernels a bit more. it supports nvme.
