00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-S GT2 [UHD Graphics 630] (rev 02)01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland [Radeon HD 8570 / R5 430 OEM / R7 240/340 / Radeon 520 OEM] (rev 87)
A confusing aspect of this is that "Oland" is indicated as part of the Southern Islands family but some sites show other information which seems to conflict. This is especially true when you try to look up the individual models listed. The HD 8570 is indicated generally as a rebranded HD 7000 series. The "Southern Islands" family has a codename alias of "Sea Islands" [according to Wikipedia].

- [update 2022/07/08] This finally doesn't segfault!!! To get to this point I ended up on Linux Kernel 5.18.10-051810-generic and Ubuntu 22.10 Kinetic Kudu along with lots of time messing with installs. Just use the amdgpu that comes with the kernel - don't try to get some external version. The DKMS pain was very high, time consuming and finally I gave up on that and found the bundled-with-kernel pieces worked fine. I am able to use all 3 of my monitors with my desktop again.
