["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Chris Rainey, thank you for reporting this and helping make Ubuntu
better. Could you please test the latest upstream kernel available from
the very top line at the top of the page from http://kernel.ubuntu.com
/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for
testing, and please do not test the daily folder)? Install instructions
are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This
will allow additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, Y, and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  15.04 freezes totally using Intel(i915) on BayTrail / ValleyView
  SoC(J2900 CPU)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Behavior:

  Ever since I first installed 15.04 back in April/May on my new DELL
  Inspiron 3646:

  Handle 0x0001, DMI type 1, 27 bytes
  System Information
          Manufacturer: Dell Inc.
          Product Name: 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:

  00:02.0 VGA compatible controller: Intel Corporation Atom Processor

  I have gained _significant_ improvements in reliability / stability by
  using various flags / 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.

  with similar results(maybe a little better than the stock i915 stack
  in 15.04).
