Uwe, thank you for reporting this and helping make Ubuntu better.

In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your understanding.

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

Status in linux package in Ubuntu:
  Incomplete

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.
