MegaBrutal, the next step is to fully reverse commit bisect from kernel
3.18-rc7 to 3.19-rc7 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Title:
  [Lenovo ThinkPad T400] kexec reboot fails

Status in linux package in Ubuntu:
  Triaged

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.
