This bug is ***NOT FIXED!*** I've just confirmed it still exists on two
systems. Note that the bug is specific to the 3.13 kernel series (it
does not affect 4.4 or other kernel series), and to the EFI stub loader
(it doesn't manifest when using GRUB 2, for instance).

Title:
EFI stub loader broken in kernel 3.13.0-101-generic (& later in 3.13
series)
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Trusty:
Confirmed
Bug description:
The EFI stub loader produces consistent boot errors when booting
Trusty starting with version 3.13.0-101-generic. This bug can be
reproduced in many ways (using efibootmgr, an EFI shell, rEFInd,
etc.). One approach is:
1) Install an EFI shell on the computer and set it as the default boot
option using efibootmgr.
2) Copy the kernel and initrd files from /boot to /boot/efi.
3) Rename the kernel file to use a .efi filename extension.
4) Reboot into the EFI shell.
5) Try to launch the kernel with a command like:
fs0:\vmlinuz-3.13.0-104-generic.efi ro root=/dev/sda2
initrd=\initrd.img-3.13.0-104-generic
The result will be a hung or crashed system. (In VirtualBox, in which
I've tested this, the VM produces a "guru meditation" and the session
terminates.)
I myself have tested only with the 3.13.0-104 kernel; however, reports
from others indicate that the problem began with the 3.13.0-101
kernel. See this Kubuntu forum thread for details:
https://www.kubuntuforums.net/showthread.php?71204-Cannot-load-latest-
kernels
Note that early on, this thread focuses on rEFInd; however, the bug
can be reproduced with other boot managers, including the EFI shell,
as described in the preceding procedure, so I do not believe this is a
rEFInd bug. rEFInd relies on the EFI stub loader to boot a Linux
kernel, and I believe it's this component that's failing. The problem
does NOT occur when using GRUB to launch the kernel. (GRUB does not
rely on the EFI stub loader.)
I have NOT encountered the problem with Xenial and its 4.4.0-series kernels
(last tested: 4.4.0-53-generic) or Yakkety and its 4.8.0-series kernels (last
tested: 4.8.0-30-generic). I have not yet tested Trusty with kernels from
series beyond 3.13.0.
