Public bug reported: In Ubuntu focal, 20.04.2, amdgpu/Xorg kernel driver crashes/resets occur with various previous-generation AMD Radeon GPUs, for instance Radeon RX 5500 XT. There is a recent fix in the mesa library.
Please see upstream mesa bug including available patch: https://gitlab.freedesktop.org/mesa/mesa/-/issues/4866 Patch is available for mesa-stable, 21.1.3 and 21.1.4. It looks like it could apply to 21.0 (which is in focal-proposed) too, with minor effort.
