Hi!
As Kevin says, it's very important to keep driver (drm-*-kmod) and 
firmware (gpu-firmware-kmod) in sync with the kernel.  If you are using 
a release, and running GENERIC, it is enough to download the packages 
with pkg and install them, but if you are using a custom kernel, or 
running STABLE or CURRENT, then you need to compile the modules 
yourself.  The easiest way is usually to run `pkg delete 
drm-fbsd11.2-kmod` and then `pkg autoremove` to remove any dependencies, 
and then build graphics/drm-kmod from ports.  This is safe to do even if 
you are using pre-built packages for the rest of the system.
