I have a custom built linux .deb kernel 5.10 that boots on bullseye and buster just fine; expect for only one of my computers, on which it hangs at "Loading initial ramdisk ...." The debian built kernels boot fine. Thoughts on what what might be the issue, how to fix or how to determine the root cause?
TIA

Compare and contrast your configuration with Debian's (/boot/config-5.10.0-3-amd64).

amdgpu is in fact loaded; just not in use. Xorg seems to be picking up the ati driver instead of amdgpu
