** 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.
