have you tried suspend/resume without having the drm-next kmod loaded?  
I have run into a couple instances of that breaking due to drm-next.

if it does work w/o drm-next then it might be worth rebuilding the pkg 
locally (via "cd /usr/ports/graphics/drm-next-kmod && make package" for 
example) and see if that fixes it.

there is also a sysctl knob i've set in the past to help in this area, 
i'll dig through my notes and see if i can find it...
