Currently kexec/kdump is not capable of making EFI run time calls in second kernel. Instead we disable EFI in second kernel and try hard not to make any BIOS calls. So do not try to import any keys/certs from db/mok. This should change once we have figured out how to make EFI run time calls in second kernel.
