[ubuntu-x] Hangs in x-swat's mesa 17.3.3-0ubuntu1~16.04.1 with radeon ?

[Dan Kegel]

Never mind, I've read mesa-devel now, e.g.
https://lists.freedesktop.org/archives/mesa-dev/2018-February/186284.html
and
https://lists.freedesktop.org/archives/mesa-dev/2018-March/189143.html
and will
a) fall back to 17.2 (from plain old ubuntu),
b) await 17.3.7 or later (from x-swat), and/or
c) try to find a repro script (e.g. a piglit test)
