hrm - i've had some mixed success actually capturing core's from the 
drm-next codebase in the past.  one thing to verify is the section here:

https://github.com/FreeBSDDesktop/freebsd-base-graphics/wiki/Testing-And-Debugging-Tips#reporting-problems

Specifically the section labeled "Common configuration issues:"  There 
are couple sysctl knob's you can tune to help capture more info.

I'd submit a issue here describing what you are seeing and attaching 
info from the core-dump if possible, or attaching the screen-shots if not:
