Thank you for your report.

If the issue is reproducible, could you please:

- Build/enable a debug kernel if applicable and attach a full backtrace
- Attach the output of pkg version -v

This looks similar to bug 225175, in which case it would be worthwhile trying the drm-kmod port/packages as suggested by Niclas in bug 225175 comment 5

FreeBSD 12.0 is unsupported. In next version is without this issue.
