The problem goes away if I disable acceleration. I haven't figured out that bug yet, but along the way I found some corrections to make based upon some auditing. 1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver and the XORG video driver differ. I've made the kernel match what XORG is using. 2) In radeonfb_engine_reset() we have top-level code structure that roughly looks like: if (family is 300, 350, or V350) do this; else do that; ... if (family is NOT 300, OR family is NOT 350, OR family is NOT V350) do another thing; this last conditional makes no sense, is always true, and obviously was likely meant to be "family is NOT 300, 350, or V350". So I've made the code match the intent. Signed-off-by: David S.
