Comment # 9 on bug 86720 from João Grego

Having the same issue with HD5650. When using mesa 10.2.8 there was no problem,
but when I upgraded to mesa 10.4.2 the entire system froze after loading a
game, either new or saved.

OS: Gentoo amd64
GPU: Radeon HD5650
GPU driver: xf86-video-ati 7.5.0
Mesa: 10.4.2
CPU: intel i3 M370
