pramathesh ambasta, the next step is to fully reverse commit bisect from
kernel 3.16 to 4.0 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:
  Black screen of death: system suddenly stopped working soon after
  upgrade to kernel 3.16.0.34-generic

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I update the kernel images from update-manager this morning on my
  Ubuntu 14.10 system running on my laptop.

  I had started backintime-gnome to take a backup of my home directory
  on an external seagate drive connected to a 4 port USB hub. This is
  something I do almost daily

  I was editing a desktop shortcut on nano when suddenly I saw a black
  screen with a lot of dumps and messages from the kernel (or what
  seemed like the kernel). The screen was frozen - no mouse movement or
  keyboard movement would restore it. I had to force a restart using the
  power button.

  This is the first time I have encountered something like this.
