hrm, i don't think this Atom chipset uses Intel HD Graphics (aka i915 
GPU's).  having said that i'm surprised it results in a panic. one thing 
you can try is to build/install a stock 12-CURRENT world and kernel on 
your system, then install the drm-next-kmod port/pkg:

$ pkg info|grep drm-next
drm-next-kmod-g20170918        DRM modules for the linuxkpi-based KMS 
components
$

this is what i'm running now since the drm-next devs have merged their 
code upstream, so no need to run code off of the drm-next github branch 
anymore!  it's possible there is some instability in that repo right now 
as i think they are updating things for linux-4.10 compatibility - so 
give the port/pkg a shot and see if that helps.
