I would suspect this ^^ commit to be the one causing the issue. Can you please revert it on top of 3.9.7 and confirm ?

Leading to the kernel being unable to change the resolution(modesetting), and X failing to start and VT switch being dead slow Cheers Emil</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
