V B, the next step is to fully commit bisect from the last known good kernel to the first identified bad one in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your understanding.

XPS 15 9530). All the patches before this one for the kernel 3.19.0 for Ubuntu 14.04 were OK. From log, the last message before freezing was "kernel: ...[drm] HPD interrupt storm detected on connector HDMI-A-1: switching from hotplug detection to polling", as you can see below: Apr 6 14:46:17 xxx-ubuntu dbus[1001]: [system] Activating service name='org.freedesktop.hostname1' (using servicehelper) Apr 6 14:46:17 xxx-ubuntu dbus[1001]: [system] Successfully activated service 'org.freedesktop.hostname1' Apr 6 14:46:17 xxx-ubuntu kernel: [ 945.147481] systemd-hostnamed[11982]: Warning: nss-myhostname is not installed.

At the moment I switched back to kernel 3.19.0-51 that does not cause this problem, but the possibility that from now on all future security patches for 3.19.0 might freeze my laptop sounds very bad. --- ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: valentinbrasov 3187 F.... pulseaudio /dev/snd/controlC2: valentinbrasov 3187 F.... pulseaudio /dev/snd/controlC0: valentinbrasov 3187 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 EcryptfsInUse: Yes InstallationDate: Installed on 2015-09-28 (192 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) MachineType: Dell Inc.
