Public bug reported:

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).

Thank you.
