If you boot with linuxrc=debug, the initrd's /init will run under set -x, i.e.
print all commands as they are executed. But you'd need a second computer and a
serial cable to save the output, so let's try something different.

You say that root=/dev/md10 actually works, so at least it's not a problem with
the md array assembly. Can you boot into the emergency shell again and do the
# mount /dev/md10 /root
# rm -f /root/tmp/mkinitrd-debug
# cat /etc/udev/rules.d/99-mkinitrd-label.rules >/root/tmp/mkinitrd-debug
# udevadm info --export-db >/root/tmp/mkinitrd-debug
# umount /root
# ln -s md10 /dev/root
# exit

Hopefully the system should continue booting after creating the symlink
manually. Please attach the /tmp/mkinitrd-debug afterwards.
