[Copy/Pasted from freedesktop.org] After testing new version of kernel on Ubuntu 17.10 installation (wayland + systemd) I discovered by chance that after suspend and unsuspend (systemctl suspend), internal monitor starts displaying image and everything works (for the first time with radeon driver).

So as a workaround I used /etc/rc.local compatibility to trigger suspend after appropriate ring level is initialized during boot(sudo chmod +x /etc/rc.local is also required).

I tested same method with 14.04 LTS with no success (so I don't know exactly what upgrade made it work).
