--- Comment #55 from kilobug@kilobug.org --- I tried the patch on the "drm-fixes-3.16" branch, but I got the same result : freeze after a while when playing a movie on mplayer -vo gl (that's the most reliable method I found to get the freeze), same with hyperz enabled and disabled (I still have radeon.audio=0).
