** Description changed:

+ [Impact]
+ 
  With the introduction of linux-modules-extra, some modules that were
  previously provided by linux-modules are now provided by linux-modules-
  extra. Since this is a non-essential package which doesn't get install
  automatically, we might be missing some 'important' modules. At the
  minimum, add all the modules that are required by the raspi DTBs and
  overlays.
+ 
+ [Test Case]
+ 
+ For example, enable the Pi PWM overlay with
+ 
+ dtoverlay=pwm-2chan,pin=12,func=4,pin2=13,func2=4
+ 
+ and then check lsmod:
+ $ lsmod | grep pwm_bcm2835
+ 
+ The module is not loaded because it is provided by the linux-modules-
+ extra package which is not installed by default.
+ 
+ [Fix]
+ 
+ Identify modules that are required by Pi DTBs and overlays and add them
+ to the linux-modules package.
+ 
+ [Where Problems Could Occur]
+ 
+ New modules might get loaded which could trigger kernel crashes.
