#415 SDDM/Kwin_wayland core dump - results in black screen on boot
Closed: Fixed by mattm. Opened by mattm.

Reopen Issue

On Framework AMD / Ryzen 7040 series platform, Fedora Kinoite 39, boots to black screen.

Journalctl shows some errors for amdgpu sdma ring time out and then performs amdgpu reset and then later Process 1282 (kwin_wayland) of user 981 dumped core.

Logging into a TTY and running startplasma-wayland starts correctly and everything appears to be working correctly.

Framework have advised that some late firmware is coming to LVFS, but nothing specific about this. I understand that AMD 7040 is a new platform.

I have attached a dump of the journal. Specific error appear at 13:40:49

I will reconfig sddm to run on X and see if it still crashes and will update the issue
journal.log

put sddm-x11.conf into /etc/sddm.conf.d/ as defined here https://fedoraproject.org/wiki/Changes/WaylandByDefaultForSDDM#How_To_Test and sddm starts correctly and is able to log into the plasma wayland session

confirming core dump appears to be caused by sddm running under wayland

ideally we need the actual backtrace from the coredump. you should be able to get it with coredumpctl gdb <pid>, after running coredumpctl list to find the PID (any unique identifier from the relevant crash should work, actually). Or you can use abrt-gui.

I believe this should be what you need
core.kwin_wayland.981.610284b90f2242af887209a2042e83af.1282.1697254849000000.zst

This is amdgpu crashing:
