hmm, I've not seen this kind of errors with the "dis -l".
It looks like the former cannot find the function or it's not a function:
case GNU_RESOLVE_TEXT_ADDR:
sym = find_pc_function(req->addr);
if (!sym || TYPE_CODE(sym->type) != TYPE_CODE_FUNC)
req->flags |= GNU_COMMAND_FAILED;
break;
what do you see with these after loading the module?

Thanks,
