I did "git reset --hard" to commit "Remove grub_bios_interrupt on 
coreboot." and then I applied only 
"grub-core/lib/x86_64/xen/relocator.S: Fix hypercall ABI violation." commit.
Now the Sid domU boot correctly, therefore the regression is caused by 
"xenfb" or "xen grants to v1" commit, should I find the exact commit 
that causes that problem or these informations are enough for you?

Thanks for any reply.
