Yes, there's a new kernel which is not limited to passwords < length 16. However, the NV OpenCL runtime fails to compile it cleanly (other runtimes such as Intel works). Note that hashcat warned you about that:
Problem is just that there's no "working" driver yet. But that's nothing hashcat can change.
You can fall back to the optimized kernel by using the -O switch.

Your device driver installation is probably broken.
