No, the stub loader should work anyway. > Is there an alternate way of getting the kernel up?

But I didn't have a platform handy to test that it resolved this issue. Modifications are required in handle_kernel_image() in arm/boot/comressed/efi-stub.c. If you don't want to wait for me to get around to sorting it, you could compare it to the arm64/kernel/efi-stub.c version and modify it yourself. / Leif ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
