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

Patrik Jansson, 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:
  [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled
  (expected 1, found 0)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  A few seconds after boot I get this message in the log (and wifi does
  not activate).

  Many things still work, but the system acts a bit confused. Sometimes
  it gets almost unsusable until reboot (and then there are more of
  those "cut here" sections in the log).

  Kind regards,
    Patrik
