Just a plain driver install on a newly installed box. The faulting
drivers did work before using the Ubuntu 16.04 kernel.
WARNING: You are using an experimental version of the media stack.
As the driver is backported to an older kernel, it doesn't offer
enough quality for its usage in production.
Use it with care.
Latest git patches (needed if you report a bug to
linux-media@xxxxxxxxxxxxxxx):
