Unfortunately I still haven't found the place where this happens cause I'm not that familiar with the code of the kernel to know by which part and when the drm initialization gets started. So I mostly did this by trail and error.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
