The attached patch works around it by disabling underrun reporting on the first frame when enabling the pipe scaler. I'm now also seeing an underrun with FBC, but that happens even without changing resolution and goes away with i915.enable_fbc=0.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
