Marked this as duplicate of bug #1567237 (instead of the other way
around) because I think that it would be probably easier to investigate
the problem using the 3.19 series of kernels, because we know 2
consecutive kernel versions in that series, which first worked and
second did not: 3.19.0-51 worked, then 3.19.0-58 did not. Also I think
is better to focus firstly on the other bug because the other bug is
higher importance and I thing that this is needed now, when both 3.19
and 4.2 series of kernels stopped working on my Laptop running Ubuntu
14.04.

Title:
After upgrade to 4.2 kernel Ubuntu 14.04 LTS randomly freezes
completely
Status in linux package in Ubuntu:
Confirmed
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.
