Not finding my own set password

[LoZio]

Just found a possible clue. Using benchmark mode with -m 9400 I get the test done. With -m 9600 I get:
Device #3: ATTENTION! OpenCL kernel self-test failed.
If I force the device to the Intel GPU (that is normally discarded saying the OpenCL runtime is broken) I found the password.
So basically using the AMD GPU (latest driver as of today) seems to work, but finds no password.
Weird tihng is that the problem is with that specific algo (9600) and not with others (9400).
