  There seems to be a bug in the efi-lockdown patch as applied on top of 
vanilla for Cosmic kernels:

  Also seems to be present for Disco as of today:

  The problem is that part of the patch modifies kernel behavior
  independently of CONFIG_LOCK_DOWN_KERNEL being set or not causing
  issues on two debugfs files on s390x.

  Vasily Gorbik has already analyzed the problem and has posted a proposed fix
