Does anyone have any tips for debugging EFI_STUB kernels when they fail to boot? I've run into BIOS before that I can't get EFI_STUB to work on but grub works fine and I'm not sure why or even how to go about getting any debug info since the bios/firmware is a block box. Is the only option to get in touch for the motherboard vendor and how they care to look into it? It's rare but happens.
