Created attachment 277835 --> https://bugzilla.kernel.org/attachment.cgi?id=277835&action=edit dmesg when crash/freeze occurred
updated from stock 4.15 kernel to 4.18-rc8. lightdm freezes on boot without boot param `nomodeset` everytime. graphical startup is proper with boot param `nomodeset`. not passing amdgpu.dc=1 as it has no effect.
