Yuriy, if the WORKAROUND doesn't work for you, then this report has nothing to do with your problem. Hence, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal:

Title:
  8086:0f31 Ubuntu 15.04-15.10 freezes totally

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Ever since I first installed 15.04 back in April/May on my new DELL
  Inspiron 3646 I have experienced frequent(daily/every-other-
  day)complete lockups(cannot even switch to console(Alt-F1,F2,etc.).

  I have determined that the issue is related to the 'i915' driver in
  relation to my GPU.

  I'm currently using intel-linux-graphics-
  installer_1.2.0-0intel1_amd64.deb from https://01.org/linuxgraphics
  with similar results (maybe a little better than the stock i915 stack
  in 15.04).

  WORKAROUND: Use kernel boot parameter:
  intel_idle.max_cstate=1

  I have gained _significant_ improvements in reliability / stability by
  using parameters in the i915 module:

  /etc/modprobe.d/i915.conf:
  options i915 semaphores=1

  and / or

  /etc/default/grub:
  GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable"

  and / or
  /usr/share/X11/xorg.conf.d/20-intel.conf:

  Section "Device"
     Identifier "Intel Graphics"
     Driver "intel"
     Option "TearFree" "1"
  EndSection

  and / or
  Disable "Intel Virtualization Technologies" in the BIOS.
