What does

 file ../kernel/drivers/gpu/drm/amd/amdgpu/amdgpu.ko

say? If its output doesn't say "not stripped", look for an unstripped version
of the module. If the file output for that doesn't say "with debug_info", try
enabling CONFIG_DEBUG_INFO (and maybe CONFIG_DEBUG_INFO_REDUCED).

If that still doesn't result in better output than ??:? from faddr2line, the
best guess so far is that there's an issue somewhere in
drivers/gpu/drm/amd/display/dc/bios/bios_parser2.c:bios_parser_construct.
