Thanks. I noticed one bug that might affect you, could you try the attached fix? Another thing is that in the working case we are using a non-SSC clock source while in the failing case we use an SSC one. So could you try booting with i915.lvds_use_ssc=0? Another difference is that the working case is with 1024x768, so would be useful to see a regdump also with 1024x768 modesetting.</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>
