Title:
  BCM43602 802.11ac Wireless regression - PCI ID 14e4:43ba

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Xenial:
  In Progress

Bug description:
  [Description]

  The wifi device BCM43602 802.11ac Wireless (PCI ID 14e4:43ba) running
  with the proposed kernel 4.4.0-155.182-generic will cause kernel
  trace[1]. However the wifi function works properly with the kernel
  4.4.0-154.181

  [Steps to Reproduce]
  1. Install ubuntu xenial, enable the proposed repository, and update the system with "sudo apt-get dist-upgrade"
  2. nmcli d wifi rescan
  3. nmcli -t -f SSID,CHAN,FREQ,SIGNAL d wifi list ifname wlp2s0 (if your wifi interface is wlp2s0), you will see the available SSIDs in your environment.
  4. nmcli d wifi connect <SSID> ifname wlp2s0 name TEST_CON

  [Expected Result]
  The AP is connected

  [Actual Result]
  You will get the message: "Error: Connection activation failed: (5) IP configuration could not be reserved (no available address, timeout, etc.)." and the kernel trace from /var/log/syslog[1]

  Sometime the system hangs when connecting to a wifi AP.
