Title:
  OOPS on beaglebone on boot of 4.4.0-36-generic under snappy ubuntu
  core xenial

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Xenial:
  Fix Released

Bug description:
  SRU:

  Problem: during installation, before configuring the network
  interfaces, netconf puts down all the network links and cpsw gets
  suspended - later on the PM code kicks and tries to access the
  suspended hardware generating an oops

  Fix: apply the patches present in:

  git://git.launchpad.net/~p-pisati/ubuntu/+source/linux
  x-master_lp1625177

  and recompile.

  How to reproduce: try to install an ubuntu-core image using the above
  patched kernel

  ----

  trying to assemble a new series 16 ubuntu core image for the
  beaglebone black i am constantly running into an OOPS on first boot.
  seemingly related to the NIC driver since the NIC does not work after
  the OOPS.
