This problem also exist on Steam_Counter-Strike:Source game.
Zhoujian : does HL2 work for you before the bisected commit? I'm having problems getting the game to work now even with older Mesa (?) I'm running on IVB and graphics are messed up already at menu screen, there are bunch of errors on the console from the game itself after I exit. I will try to see first if this is just problem with my environment.
I expect that this is the same bug as https://bugs.freedesktop.org/show_bug.cgi?id=76616 and I've got a patch waiting for review to fix it.
