Latest Beta release 3.6.0+268 issue with PDF 1.7

[Jiminy]

I've downloaded  hashcat-3.6.0+268 and am attempting to try to crack the PDF 1.7 hash example listed in the wiki.
My exact command line is:
HC64 -m 10700 -a 0 [copy and pasted the hash example from the wiki here without the brackets]  word.txt --status --status-timer=3
the word.txt file contains the word hashcat (5 of the 6 entries), as is supposedly the password for all the example hashes listed as per the wiki.

I'm running windows 10 x64 with two NVIDIA GTX-960's on a 6 core cpu.

I've had to apply the time-out patch in order for 3.6.0+268 to run, but I still get errors that:
1.  when running the benchmark "nvmlDeviceSetPowerManagementLimit(): Insufficient Permissions", which per ATOM, can be disregarded.
2. Device 1 and 2 open cl kernel self-test failed (see below)

I've installed the latest NVIDIA driver that supports the GTX - 960's

Here is a screen copy of the event:

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.

I assume the PDF 1.7 hash is extremely slow from the way it acts.

The last beta version of 3.6.0 that worked was 3.6.0+200.  No version after 3.6.0+200 will find the password.
I even tried putting the hash in a text file. Still does not work.  What am I doing wrong??? or has the code changed???

Anyone have any ideas?

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:

* 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.

Thank you Atom.  Appreciate the response.  I applied the "-O" switch and it worked.  And yes, I observed the "failed self-test" error message, but didn't know the ramifications.

Thanks again.  Hashcat is a fine piece of software.  Keep up the good work.!!!!
