[Bug 107213] [amdgpu/DisplayPort] KDE Wayland session is segfaulting right after login

See attached dmesg output. Once thing to note, I consistently get a black screen after boot (the monitor goes into a sleep mode). I need to turn monitor off, turn it back on, switch to tty1 (then monitor turns on), then log in there and restart sddm. Only then sddm appears on tty7. After that, Wayland session log-in fails (I tried a couple of times which is reflected in dmesg).

First try didn't result in segfault in dmesg, just in *ERROR* REG_WAIT, but second attempt also added as segfault.
