This is in response to December's
<https://lists.freebsd.org/pipermail/freebsd-x11/2015-December/017039.html>;
(the list server seemed to omit attachments from January's
<https://lists.freebsd.org/pipermail/freebsd-x11/2016-January/017103.html>).

dmesg output from PC-BSD 11.0-CURRENTNOV2015, which does not suffer

dmesg output from a verbose boot of PC-BSD 11.0-CURRENTFEB2016:

December, January and February distributions of CURRENT are very prone
to blackouts with this hardware. Maybe easiest to reproduce by
launching GNOME System Monitor; for me a blackout occurs almost
immediately, or within a few seconds.
