It seems your're not actually using drm-*-kmod. /boot/kernel/i915kms.ko is part
of ancient in-base drm2 which is based on Linux 3.8 drivers.
According to pkg-message you need to add kld_list="/boot/modules/i915kms.ko" to
rc.conf(5). It'd unlock VAAPI via libva-intel-driver as well. ;)

0116 is SandyBridge (Gen6). drm-kmod should work fine but upgarding to FreeBSD
12.* may bring more stability.
In general, userland drivers (e.g., mesa-dri, xf86-video-{intel,amdgpu,ati},
modesetting) in ports/ have to support everything but the level of support
degrades the farther away one strays from what contributors dogfood (i.e.,
-CURRENT):
- in-base drm2 aka drm-legacy-kmod are a complete abandonware
- drm-fbsd11.2-kmod is abandonware that still receive minor QA/fixes
- drm-fbsd12.0-kmod is abandonware that still receive minor QA/fixes
- drm-current-kmod is stable and receives LTS upstream fixes
- drm-devel-kmod is best maintained but can be unstable shortly after major
updates

Set "AccelMethod" to "SNA" (aka Sandybridge New Acceleration) in xorg.conf(5)
for more performance. SNA is default upstream, so maybe more stable.

Try modesetting (part of xorg-server package). Either remove xf86-video-intel
or set "Driver" to "modesetting" in xorg.conf(5).
