Help debugging iPXE EFI kernel boot failure

[erikj]

Good morning. Thanks so much for getting back to me. Since posting this (it was my first forum post so I couldn't update this earlier)... I think I've learned you're correct.

I have 3 scenarios

A opensuse13.2 kernel boots fine (a modern EFI kernel)
A rhel6.6 kernel gives an error (I later found this kernel has CONFIG_EFI but not CONFIG_EFI_STUB set)
A sles11sp3 kernel hangs (but does have CONFIG_EFI_STUB).

I had enabled debugging and indeed saw the "is not EFI" message for the rhel66 case.

It looks like I'm too early to be able to use this particular function.

Thanks again for getting back to me and best wishes.
