I applied it on top of the first patch. Hope that was OK. I ran xtrace, see stutter.txt. It didn't obscure the stutter, although it took a few seconds longer to navigate the menus to start playback. Before this test, I did reboot without drm.debug set. Hope that was OK. Let me know if you want the drm.debug=0x7 output and/or ftrace. I've never done an ftrace. Something new to learn about.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
