These messages are printed by the "shim" UEFI application:

  https://github.com/rhboot/shim/blob/master/shim.c

probably when it attempts to load "grub".

I suggest reporting the issue at
<https://github.com/rhboot/shim/issues>. (Perhaps this issue has been
reported already, I'm not sure.)

Thanks
