3.16 is too old to support (though it wasn't when you filed the bug... sorry). The good news is that *lots* of fixes went into the kernel and Mesa in the last two years. In the future, please tell us how to reproduce the hang (if it's not reproducible, there's very little we can do about it) and at least the output of "glxinfo | grep Mesa".
