Checked with linux-3.13.2-1 - everything is ok. install again linux-3.13.2-2 and reinstall gummiboot - boot failed.

0001-revert-avmfritz-breaker.patch is bad patch! :) Revert it or fix if possible

Are you sure you're not another victim of  FS#33745 ? The patch merely reverts some ASM details to the state of 3.12.

As it stands, we have a dozen people who are randomly able or unable to boot the kernel with EFISTUB, just depending on pure luck.

In addition, none of the functions changed in that revert are used anywhere in the EFI code.

I'm booting from UEFI with gummiboot last half year and it is first time I can't boot. I checked twice: linux-3.13.2-1 - booting ok always, linux-3.13.2-2 - fails everytime.
May be it related to  FS#33745 , I'm not sure.

I'm pretty sure this is the  FS#33745  bug, all is random and this patch does not affect EFI at all.
You need to compile the kernel yourself too see if you suffer from the mentioned bug report.
Sometimes kernel work sometimes not.
