+Subject: [PATCH] kern/efi/init.c: disable inside lockdown and shim_lock
+ verifiers
+
+The lockdown support[1] and secure boot detection[2] have been added to
+grub 2.06. These verifiers are registered when UEFI Secure Boot is
+enabled. Unfortunately, they conflict with the current MOK2 Verify
+mechanism. So disable them when enable SELoader.
+
+Fixes grub error:
+error: failed to verify kernel /bzImage
