Hm, the only thing I can think of is the auth problems we have with 
amdgpu starting with 4.11

https://github.com/FreeBSDDesktop/kms-drm/issues/33

but that didn't break Weston, only Xwayland/Vulkan/OpenCL/some games.

Another breakage I remember is with amdgpu's new (4.15) display code 
(compat.linuxkpi.dc="1" in /boot/loader.conf): 
https://github.com/myfreeweb/weston/commit/400fdc3c1c031bac380ef93649ecfbe48ec5b912 
But you're on 4.11, so you don't have that option.

Double check what's different betweet your Intel and AMD boxes, are the 
permissions/groups correct, etc.
