I'm experimenting with booting root fs from LVM volume inside the raid (mdraid superblock 1.x) via UEFI with GRUB2. Also I'm using Xen hypervisor.

From grub command line I can see my lvm volume (ls command) but I got kernel panic due to "unable to mount root fs". I saw a note in this article telling it's probably impossible to boot root fs from raid via UEFI, but I don't understand the reason why not.

Is it possible to boot linux with this configuration without the initramfs (which I don't won't to use)?
