It is here - (return checked in refit efi shell and gui)
Can't go any further until that is fixed.
kern/x86_64/efi/startup.S
-----------------------
This hangs -
codestart:
movq %rcx, EXT_C(grub_efi_image_handle)
movq %rdx, EXT_C(grub_efi_system_table)
+ret
call EXT_C(grub_main)
ret
-------------------------
This returns -
codestart:
+ret
movq %rcx, EXT_C(grub_efi_image_handle)
movq %rdx, EXT_C(grub_efi_system_table)
call EXT_C(grub_main)
ret
--------------------------
Would really like to see the solution for the imac8,1.
