I have same problem with last driver version 20190717-1, in my case it's a related problem with HDMI connection, if I boot with HDMI plugin freeze in the same time.
If I plug after login in X session, system freeze: [drm] amdgpu_dm_irq_schedule_work FAILED src 2 I'm not sure if the problem comes from firmware-amd-graphics or linux-image-amd64_4.18+99_amd64.deb Let me know to open a new bug if required. Thanks.
