With the series binding block devices after initializing the UEFI
sub-system works fine. Also unbinding is reflected in the EFI devices.
But this series breaks UEFI compliance. All block devices must be probed
before booting. Without this GRUB will not be able to read the boot
partition with vmlinuz and initrd.
Will you provide the missing patch?
