Public bug reported:

This issue has been resolved upstream and is described in
https://bugzilla.kernel.org/show_bug.cgi?id=117391

The current Ubuntu Xenial Xerus kernel (4.4.0-21.37) is built with a
version of the iwlwifi driver which supports firmware version up to
iwlwifi-8000C-19.ucode.  However, the matching linux-firmware package
ships with the -16.ucode version of the firmware, which contains this
bug.

The next stable version of the firmware after -16.ucode is -21.ucode,
but is not supported by the version of the iwlwifi driver in the 4.4.0
kernel.  In order to fix this issue, either the minor version of the
firmware (-19.ucode) needs to be included in the linux-firmware package
or the iwlwifi driver in the kernel package needs to be upgraded with a
backport of the iwlwifi driver new enough to support the -21.ucode
firmware.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Incomplete
