Title:
  X freezes since upgrade to linux-image-4.2.0-35-generic

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to linux-image-4.2.0-35-generic from wily-security my
  X freezes after a while (random time, but never more than 2 minutes).
  If when the GDM prompt I switch to the terminal, then the laptop runs
  smoothly.

  Booting with 4.2.0-30-generic works fine.

  Sound quite related to
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1527115 But I
  tried with the Kernel Mainline Builds (both linux-
  image-4.4.0-040400-generic and linux-image-4.5.0-040500-generic).

  The problem is I have no way to capture the logs when the computer
  freezes... so I have no more details to debug where the issue actually
  comes from. My guess were the graphical drivers; I tried xserver-xorg-
  video-intel both the official version and the PPA
  (2.99.917+git20151202.da9ad388-0ubuntu0sarvatt) with the same result.
