--- Comment #33 from Andrew Randrianasulu randrik@mail.ru --- I also have affected system and wanted for ages to see it fixed (with or without my help). unfortunately, even if I still can try and load old linux distro where last working fglrx (proprietary driver) was working - I have no idea what to do next - even mmiotrace format apparently changed from 2.6.29 kernel era, and here i fear some more tracing will be needed (and tools for userspace tracing also appear to bitrot or not even properly support this GPU).
i tried to appear on #radeon but everyone was busy there (I think this situation will continue more or less due to new bug flow, new hardware, new features, other users and developers also wanting various levels of help). may be setting special 'hackday' for this or other specific bugs will help? if you like the idea - please reply (I tend to read dri-devel and mesa-dev ML).
Thanks in advance!
