I ended up also that same commit after bisecting from current 3.8 master.

01:05.0 VGA compatible controller: ATI Technologies Inc 760G [Radeon 3000]
It is ASUS M5A78L-M/USB3 with integrated GPU.

I cannot even boot unless graphical boot is removed from Fedora 17 boot 
options (rhgb quiet). Random GPU crashes still.

regards
Antti
