Analysis thus far is that we do a completely bogus modeset on the 2nd crtc, but while actually disabling the 1st crtc. Hence caller supplies no mode, and we fall over with a NULL deref trying to prepare the modeset on the 2nd crtc. Above patch might shed clue on why we try to do that bogus modeset.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
