MegaBrutal, the next step is to fully commit bisect from kernel 3.13 to
3.16 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue.  Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note,
finding adjacent kernel versions is not fully commit bisecting.

Thank you for your understanding.

Title:
  kexec reboot fails

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After release upgrade to Utopic, when I reboot with kexec (simply with
  "reboot" command), my computer cold reboots after "Starting new
  kernel" (i.e. I need to get through the POST and GRUB), instead of the
  new kernel being loaded. Previously I didn't experience problems with
  Trusty.

  It matters which kernel I try to boot, while it doesn't matter what
  kernel I kexec from, and which version of kexec-tools I have.

  I can't boot 3.16.0-25, nor 3.18.0-031800rc6 from any installed
  kernels, while I can boot 3.13.0-39 from any kernels without any
  problems.

  I tried to downgrade kexec-tools from 1:2.0.7-1ubuntu2 (utopic) to
  1:2.0.6-0ubuntu2.1 (trusty), but it made no difference.

  I have a Lenovo Thinkpad T400. I didn't experience the same on my
  other machines, so I suspect some hardware-dependent issue.
