Well he can just try to revert this one again, Kodi seems to does not like that: http://cgit.freedesktop.org/mesa/mesa/commit/src/gallium/drivers/radeon/r600_buffer_common.c?id=7b4276d7acf2e0f77044cb50caa6ad936fa78786 @Michel I guess this should be reverted again as Valley does not stutter with 3.19 kernel.
