Previously kdump would work with SGI UV machines as it used "noefi". Now kexec by default thinks that efi is enabled and 1:1 mappings are in place and that does not work with SGI UV machines. So just providing --noefi is not enough. Somebody needs to automatically figure out that this SGI machine does not contain 1:1 mapping and hence need to fall back to old mode. --noefi is good for override.
