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

Jurrian Fahner, 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:
  Low screen resolution and no networking after kernel update

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After kernel update yesterday, a reboot was requested. 
  After reboot the screen resolution was set to 800x600 and the network manager didn't show any network adapters. 

  When I boot with the kernel image "4.2.0-16", everything works as expected. This is a good work around until the problems are fixed.
