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. --- ApportVersion: 2.14.1-0ubuntu3.21 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: rodsmith 1675 F.... pulseaudio CurrentDesktop: LXDE DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=561add6d-844e-4428-8378-d92bb112d0fc InstallationDate: Installed on 2014-04-27 (960 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) IwConfig: eth0 no wireless extensions. lo no wireless extensions.
