Same for me. And :
# dpkg -l amd64-microcode
ii amd64-microcode 3.20240820.1~deb12u1 amd64 Platform firmware and microcode for AMD CPUs and SoCs
But I got :
# cat /proc/cpuinfo | grep microcode
microcode : 0xa601206
[x cpu nb]

I also build my custom kernel. I use sources from 6.10.6-1~bpo12+1. I
have no CONFIG_MICROCODE_AMD but a CONFIG_MICROCODE set by
CONFIG_CPU_SUP_AMD. Which kernel version do you use ?
