Just to clarify. KALLSYMS is required to figure out the symbol addresses on a kaslr system. There's no way to look them up in a System.map file or the object file, since the addresses aren't going to match.
Your symptoms really sound like you might not have KALLSYMS enabled.
I wonder if we have a "select KALLSYMS" as part of RANDOMIZE_BASE, since you need it for debug messages too (random hex numbers aren't too useful ;)
