They are also unwilling to say whether the DRM bug that attempts to perform a hard reboot (i.e., without so much as sync(), let alone an orderly shutdown with UFS unmounts, etc.) in response to a hung GPU has been reported upstream. It ought to be a FreeBSD Foundation project to drum up money to hire a professional GPU programmer (perhaps part-time) and a full-time programmer for CPU-side graphics support. The latter could devote some of his time toward managing the graphics team's projects and objectives. With these, perhaps FreeBSD could finally have native graphics support instead of having to import ever more of the LINUX kernel into FreeBSD in order to have graphics, even buggy graphics, at all.
