What does "after this change" mean when the change was made more than a year ago, and you apparently have local modifications to the driver...? You have things like i915.enable_initial_modeset=1 which never existed upstream, and we have zero clue how things like that could interact with what we're doing. We can't be responsible for how our changes might break code that is not under our control! So please do try to reproduce with upstream code as suggested by Lakshmi in <a href="show_bug.cgi?id=109651#c1">comment #1</a>.</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> <li>You are the assignee for the bug.</li> </ul> </body> </html>
