Title:
  [Xenial] Update to kernel 4.4.0-112-generic make the system failed to
  boot with enabled BIOS SecureBoot mode

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Triaged

Bug description:
  [Description]

  After updating from 4.4.0-111 to the latest 4.4.0-112, the system with
  enabled BIOS SecureBoot mode will fail to boot because of "Operating
  System Loading signature not found in SecureBoot database" prompted by
  BIOS (See the attachment picture)

  [Steps to Reproduce]

  1. Prepare a system installed with 16.04.1 and enabled BIOS SecureBoot mode.
  2. Update the system (over the Update manager GUI or "apt-get dist-upgrade")
  3. Reboot the system to make the update effective.

  [Expected Result]

  The system gets ready to use after reboot.

  [Actual Result]

  The system stops at the BIOS stage with the prompted message
  "Operating System Loading signature not found in SecureBoot database"
  prompted by BIOS (See the attachment picture)

  [Reproducible Systems]

  So far I reproduced this issue on the following machine:

  CID 201410-15915 - Dell XPS 13 9343
  CID 201610-25147 - Dell OptiPlex 7450 AIO
  (potential candidate[1]) - CID 201610-25144 - Dell Precision 5520
  (potential candidate) - CID 201606-22338 - Dell XPS 13 9360

  [1] "potential candidate" means the system failed to boot after system
  update but have not identified it was encountered the same issue.
