I installed yesterday evening linux-image-4.5.0-040500rc7-generic_4.5.0-040500rc7.201603061830_amd64.deb linux-headers-4.5.0-040500rc7-generic_4.5.0-040500rc7.201603061830_amd64.deb
and left the laptop on during the night (without suspending) and in the morning was still not frozen. Usually with the 4.2 kernel it would have frozen over night and it have frozen during this morning, but with the 4.5.0-040500rc7 the laptop did not freeze yet. However, with 4.5.0-040500rc7 I cannot use the proprietary bcmwl driver for my wireless card and the software update does not work properly and while installing the above linux headers package it complained about missing dependencies, howver it did install it. So I am keen to try a lower version kernel, like v4.4.5-wily hoping that it will still work (no freezes), but t the same time that I may be able perhaps with it to also use the proprietary bcmwl driver and I will hopefully get no software update problems a I get now with 4.5.0-040500rc7. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1552333 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.
