V B, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  After upgrade to 4.2 kernel Ubuntu 14.04 LTS randomly freezes
  completely

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am not sure whether this is related to Xorg because of following:

  Today it happened a few times this complete freeze. Before today never
  happened. Today I did a normal system update in the morning, then a
  ditro upgrade which just upgraded a few unimportant packages, then the
  first freeze happened. Later I upgraded the kernel from 3.19.0 to
  4.2.0 and after that a few more freezes happened. I attached the apt
  log generated today and including the last update yesterday:
  apt_log_for_day_with_upgrade_to_kernel4.2.log. Each time this
  happened, before freeze I saw in the log something like:

     9492 Mar  2 14:00:08 my-ubunty kernel: [ 2514.659171] [drm] HPD
  interrupt storm detected on connector HDMI-A-1: switching from hotplug
  detection to polling

  And once or twice I saw right after that something like:

     9493 Mar  2 14:01:13 my-ubuntu compiz: pam_ecryptfs: seteuid error
  Then some binary content

  I also use disk encryption (the one from Ubuntu).

  Each time the freezing happened, the mouse and keyboard weer dead and
  the screen was frozen in whatever content was displaying at that
  point. So the only think I could do is to press the power button for 5
  seconds.

  I upgraded from 3.19 kernel (linux-generic-lts-vivid) as follows:
  $ sudo apt-get update
  $ sudo apt-get install linux-generic-lts-wily

  Thank you.
