After upgrading from gummitboot 6 to 7 all I get is a black screen with a cursor on it.. Before the upgrade I had a menu and could boot. I down graded back to gummiboot-efi-6 and it works again.

My partition layout is: /boot/efi/ gummiboot.efi vmlinuz-linux.efi initramfs-linux.img are here.
/boot/efi/loader/entries/arch.conf and arch-fallback.conf

I think this issue is specific to Asus systems. Many other users (mostly Lenovo) have confirmed gummiboot-efi-7 working in their systems. Report this issue to the upstream author Kay Sievers at .

Info forwarded to upstream (Kay Sievers ,>)

There seems to be some issue with gummiboot when one entry filename is an extension of another entry filename. Can you try renaming /boot/efi/loader/entries/arch.conf to /boot/efi/loader/entries/arch-core.conf or something like that and also change "default arch" to "default arch-core" in /boot/efi/loader/loader.conf, and try again?

Kay sent a patch. The patch did not fix the problem. He then sent me the binary compiled on his system, which works.
So if installed for the repos or built on my system they fail.
Here is the patch

Also I did try the renaming of the config files and it does not help.

I had the same issue with v7, but for me the current gummiboot git (which was released as v8) works.
Comment by Dennis Anderson (tweezerhead) - Friday, 02 November 2012, 09:53 GMT
With v8 I get a menu showing only EFI shell which I did not even create a config file for. My arch-core and arch-fallback are not in the menu. They only show with v6 or v7 compiled on Kay Sievers system.

Yep, same issue here with v8. But I think that's a different issue.
Comment by Tobias Powalowski (tpowa) - Monday, 05 November 2012, 14:48 GMT
Status on v8?
Comment by Dennis Anderson (tweezerhead) - Tuesday, 06 November 2012, 16:31 GMT
v8 status. With shellx64.efi in the efi directory, and only arch config files in loader/entries all I get at boot is the EFI SHELL selection. It will boot the shell. If I remove the shellx64.efi binary. when I boot I get "loader/entries/*.conf needed". It then boots the next entry in efibootmgr boot order.

v6 and a v7 sent to me by the developer still work as expected.

Should all be fine now with patched gnu-efi-libs and rebuild gummiboot package.

I can confirm that all v8 versions "work" for me (package from extra, gummiboot-efi-git from AUR and self-compiled from git). With "work" I mean they do not immediately lock up the machine.

However, I still have the issue that no entries are present, so only the defaults can be chosen (EFI default loader, EFI shell, Windows bootloader). So I can't boot Arch with gummiboot, unfortunately.

I tried adding some debug Print()s, however everything I change makes the machine lock up immediately :/ Not sure what's the best way to debug this...
