dmesg log with amdgpu crash
As a workaround for the problem described in bug 204363, I am using the
parameter "drm.edid_firmware" parameter to override the EDID.
This EDID seems to work fine, if I log in to my desktop (GNOME 3.32 unter
X.org) before plugging in the HDMI cable to the projector. But when the HDMI
cable is plugged in during boot, or when launching Wayland or X.org when the
cable is plugged in, the graphics driver crashes with the following error
message:
kernel BUG at drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:6264!
Full dmesg log attached.
