I have tried with the grub kernel cmdline mentioned, but the freeze is
still happening at 'modprobe amdgpu'

Is there an explicit list of kernel module dependencies that I could
check in our kernel defconfig?

I have also added Qiang, in case he may have ever seen the issue in
his former Android experience
