Latest Beta release 3.6.0+268 issue with PDF 1.7
#2
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:

Quote:* Device #1: ATTENTION! OpenCL kernel self-test failed.

Your device driver installation is probably broken.

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.
