Radeon graphics work with 4.19.0-8 but not 4.19.0-9
I installed a Radeon WX 3100 a few days ago on my buster system. It failed to bring up the X server. I installed the proprietary drivers from AMD's site, but still no dice. Just for fun I tried to boot the previous kernel 4.19.0-8 and the system worked fine.
I have install the amd-graphics-firmware from buster backports version 20190717-2. Also installed xserver-xorg-video-amdgpu version 18.1.99+git20190207-1.
I have reconfigured the kernel and ran update-initramfs. Also purged the amdgpu xorg driver and reinstalled.
Any ideas on how to get the system to run X with the 4.19.0-9 kernel.
