I'm having the same problem with a new Gentoo install, but with a twist. I am using lvm2 with a vg of two whole disk pvs and raid1 lvs for /, /boot, and /boot/efi. Since I'm not using mdadm, the script in comment #18 doesn't work for me, and I'm not able to modify it for my case, although I try a bit more.
