The first thing I noticed in your post was "grub-efi-amd" - I thought on
modern UEFI systems, you used UEFI and not grub to boot linux ...
But, as another datapoint, I boot from almost exactly the same setup as
you, two mirrored disks on a GPT/BIOS system. My grub entry is
menuentry 'Gentoo GNU/Linux, with Linux 4.4.6-gentoo' --class gentoo
--class gnu-linux --class gnu --class os $menuentry_id_option
'gnulinux-4.4.6-gentoo-advanced-ab538350-d249-413b-86ef-4bd5280600b8' {
load_video
insmod gzio
insmod part_gpt
insmod part_gpt
insmod diskfilter
insmod mdraid1x
insmod ext2
set root='mduuid/69270eaca840f6e70199064bd5863c5d'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root
--hint='mduuid/69270eaca840f6e70199064bd5863c5d'
ab538350-d249-413b-86ef-4bd5280600b8
else
search --no-floppy --fs-uuid --set=root
ab538350-d249-413b-86ef-4bd5280600b8
fi
echo 'Loading Linux 4.4.6-gentoo ...'
linux /boot/vmlinuz-4.4.6-gentoo
root=UUID=ab538350-d249-413b-86ef-4bd5280600b8 ro domdadm
echo 'Loading initial ramdisk ...'
initrd /boot/initramfs-genkernel-x86_64-4.4.6-gentoo
}
Cheers,
