A routine #Debian testing/unstable upgrade turned into 90mins of debugging when #amdgpu failed to load #firmware and dumped me at a text-mode console login prompt. Downgrading `firmware-amd-graphics` made no difference, but using an older kernel (5.7.0-1 instead of the latest 5.7.0-2) worked to get me to a graphical desktop. I reported the #regression #bug.
Seemed fixed in 5.7.0-3.
