Peter Matulis, regarding the driver crash noted in the Bug Description,
the next step is to fully reverse commit bisect from kernel 4.2 to
4.3-rc1 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:
  [Ubuntu 15.10] Intel Display i915 driver crashes, Asus Zenbook 303LA

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Wily:
  Incomplete

Bug description:
  My Asus Zenbook 303LA (UX303LA-DS51T) eventually gets a corrupted
  display. Everything repeatedly shifts horizontally. I found the
  following in the kernel log. The corruption does not have a 1:1
  relation with the occurrence of the error however.
