Title:
  System freeze when going into suspend after “rmmod cx23885 cx25840”

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When the system (Ubuntu 16.04 LTS with Kernel 4.4.0-28) goes into
  suspend (hybrid-sleep with systemd), I get sometimes (around every
  fifth time) a system freeze. In the other cases, everything works fine
  before and after the suspend with the system and DVB-C/T card DVBSky
  T982.

  I using the following configuration to remove both modules for my DVB
  card, otherwise the card would not work after suspend.

  [Unit]
  Description=Restart DVB services
  Before=sleep.target
  StopWhenUnneeded=yes

  [Service]
  Type=oneshot
  RemainAfterExit=yes
  ExecStart=/sbin/modprobe -r cx23885 cx25840
  ExecStop=/sbin/modprobe cx25840 ; /sbin/modprobe cx23885

  [Install]
  WantedBy=sleep.target

  I have nothing installed what are using the modules at the moment (e.g. like tvheadend).
  I had the problem also with Ubuntu 14.04 and Vivid Kernel 3.19 a couple of month ago. Only the installation of the closed source driver from DVBSky could fix the problem under Trusty.

  May the issue is related to Bug #1532412.

  Please find attached the syslog part with the logging and error
  messages before my system freeze.
