  Kernel 3.19.0-58 freezes Ubuntu 14.04 on Dell Inc. XPS 15 9530

Status in linux package in Ubuntu:

Bug description:
  The latest security patch for  3.19.0 for Ubuntu 14.04 started
  freezing my laptop (Dell Inc. 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'

  se install nss-myhostname!

  Apr 6 15:07:35 xxx-ubuntu kernel: [ 2222.796696] [drm] HPD interrupt storm detected on connector HDMI-A-1: switching from hotplug detection to polling

  This is the same symptom as described in the bug
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1552333, which is
  a bug raised for 4.2 kernel running on Ubuntu 14.04 using the same
  laptop and the same Ubuntu installation as for this bug.

  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.
