** Description changed:
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.
