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.
