No change. I actually upgraded gnu-efi first and then recompiled
efilinux-git (upto 	"bzimage: Fix EFI to e820 memory type mapping"
commit). Still the system hangs with

x86_64 UEFI Shell (Beta)

x86_64 UEFI Shell (Old)

efilinux loader 0.8
(system hang)

Shell binary links at
https://help.ubuntu.com/community/UEFIBooting#UEFI%20Shell .

Just FYI the build script I use for gnu-efi and efilinux-git are
https://aur.archlinux.org/packages/gnu-efi/PKGBUILD and
https://aur.archlinux.org/packages/efilinux-git/PKGBUILD respectively.
They are simply bash scripts so are easy to understand. Compilation
was done in Archlinux x86_64 Linux 3.0 kernel with gcc-multilib 4.6.1
.

Also Fedora's gnu-efi package seems to use lots of patches (
http://pkgs.fedoraproject.org/gitweb/?p=gnu-efi.git;a=tree ) . Can
somebody ensure the patches are included upstream so that other
distros also benefit? Thanks in advance

Regards.
