The best course of action would be to make a PR. The PR should contain a full description of your hardware, full "pciconf -lvbe" output, description of actions that reproduce a kernel panic, /var/log/Xorg.0.log just before kernel panic and then a link to the core dump itself. To obtain an initial core dump, please follow these instructions: https://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/ker= neldebug.html#kerneldebug-obtain You can submit a PR here: https://bugs.freebsd.org/bugzilla/enter_bug.cgi After the initial PR has been submitted, the developers will sooner or later contact you and provide more information on what need be done. Do note that I have an Ivy Bridge laptop, and the i915kms + X.org work flawlessly without any problems. It is rather peculiar that it core dumps on your laptop with the same chipset. Thus it is just best let the developers figure it out.
