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

Patrik Jansson, the next step is to fully reverse commit bisect from
kernel 4.2 to 4.3 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

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
