Mono based games just stop after opening a window.

AMD HD7750 Cape Verde
Kernel 3.9 with drm-next-3.10-2
mesa from git
llvm from svn
32bit versions as well

Can be seen in Bastion, Rochard, Kestrel Space Program, or in the linux version
of this free game: http://www.desura.com/games/battlemass

looks just like https://bugs.freedesktop.org/show_bug.cgi?id=60929, but llvm
shared or not doesn't make a difference.
