I built my amd64 kernel a week or so back with this KERNCONF: include GENERIC ident DWARF options KDTRACE_FRAME options KDTRACE_HOOKS options KDB options DDB options DDB_CTF Can you check with ctfdump if you objects actually have CTF information in them? Something like this: # ctfdump -S /boot/kernel/kernel .... # ctfdump /boot/kernel/kernel | grep ...
