I bisected the regression into 0a67361dcdaa ("efi/x86: Remove runtime table address from kexec EFI setup data"). v5.7-rc1 caused a reboot loop on another Intel Core based prototype HW. Reboots also on top of 0a67361dcdaa but boots fine with that commit reverted. Our test system uses kexec to boot the test kernel. These two machines got regression with v5.7-rc1. We have also others that boot fine. -- Jarkko
