Description:
Since kernel 3.8.X, I can't create entries in my UEFI with 'efibootmgr' command.
It was working fine with kernel 3.7.X.

But recreate a same entry print this error :
** Warning ** : Boot0000 has same label ArchLinux
And do nothing changes.

Additional info:
* package version(s) :
extra/efibootmgr 0.6.0-1
core/linux 3.8.5-1 (base)

* config and/or log files etc.
x86_64 BIOS EFI AMI (motherboard : Asus P8P67)

Steps to reproduce:
In a root terminal, I do this :
# echo "root=UUID=792e28b7-7115-4879-9f80-29c517b4ca9f ro quiet nomodeset vga=0 fglrxfb fbcon=scrollback:512k resume=/dev/md1 rootfstype=ext4 add_efi_memmap initrd=\EFI\arch\initramfs-arch.img" | iconv -f ascii -t ucs2 | efibootmgr --verbose -c -g -d /dev/sda -p 2 -L "ArchLinux" -l '\EFI\arch\vmlinuz-arch.efi' --append-binary-args -
Or :
# echo "initrd=\EFI\arch\initramfs-arch.img root=/dev/md0 ro quiet" | iconv -f ascii -t ucs2 | efibootmgr --verbose -c -g -d /dev/sda -p 2 -L "ArchLinux" -l '\EFI\arch\vmlinuz-arch.efi' --append-binary-args -
And there are no output.
Then, when I use this command, to verify :
# efibootmgr -v
There is not the entry who was created.

Efibootmgr is crucial for EFI Boot Stub. Without, it is not possible to boot without using a bootloader.
