I think I fixed most of bus_dma related bugs in 7-stable. Some users still suffer from instability issues but I guess it's different one that came from lack of documentation of PCIe based controllers. If you are not running 7-stable, try it 7-stable first and let me know how it goes. -- Regards, Pyun YongHyeon
