Title:
  ecryptfs_decrypt_page: Error attempting to read lower page; rc = [-4]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  ecryptfs_decrypt_page: Error attempting to read lower page; rc = [-4]

  ecryptfs_readpage: Error decrypting page; rc = [-4]

  I dont' have this issue showing in dmesg when using 3.19 kernel,  only
  with later kernels.  Is it related to selecting encrypted home on
  install or something?

   I don't notice any issues with performance because of it or have any
  other error messages.  I am using default ubuntu xenial 16.04 with
  unity.
