drm-devel-kmod-4.16.g20180824 hangs my laptop

[Jakob Alvermark]

Hi,


When I updated to drm-devel-kmod-4.16.g20180824 my laptop hangs. 
Previous version of drm-devel-kmod worked.

kld_list="/boot/modules/i915kms.ko" in /etc/rc.conf

When it boots and the modules load the screen goes blank (backlight 
still on) and the machine is totally non-responsive.
