When I run with Fedora kernel version 4.11.11 the video card works properly, using the amdgpu kernel driver. However, once I upgrade to a newer kernel in the 4.12 or 4.13 series, my display goes blank during boot and stays that way for a long time. The monitor appears to be getting sync, because it doesn't go to sleep, however there is nothing visible on the screen. Eventually, error messages are displayed and the system never boots fully. I've attached logs showing both a good and a bad startup. For some reason, in the "bad case", I got two xorg log files, so I've attached both. Please let me know if there is more information that I can collect to help in debug.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
