Any one else gets random freezes or gets stuck on inferno?

[Kaospiloten]

So i have recently updated to the newest amd driver, because otherwise i couldnt run the game. So obviously the update prevented me from launching with old drivers good job valve :)
But i just played one premier match at inferno and got various freezes during the game and get stuck on the floor several times and i could get stuck there until it automaticly jumped me up and i got loose.

So does any one else get this bug or what can i call it?
Kind of annoying, never happened during the old driver.. Might be driver related? i honestly dont know :/
