oclHashcat bug?
#1
Great work with oclhashcat. Finally a GPU cracker that support some Wordlists. From the few test I have done, the speed is amazing. With 1 GPU, I have cracked in minutes what it took me several hours with 3 CPU. I have however a question or a bug report. How do you select many GPUs for the cracking? Here's what I have as GPUs:

GPU 1: Cheap motherboard CUDA gpu
GPU 2: GTS250
GPU 3: GTX260

Here's the setting I have tried:

-d 1 --> Works but slow (device 2 and 3 are skipped)
-d 2 --> Works fast (device 1 and 3 are skipped)
-d 3 --> Crash (None are skipped until it crashes on #3)
No -d --> Crash (None are skipped until it crashes on #3)
-d 1 -d 2 --> Works fast (device 1 and 3 are skipped)
-d 12 --> All skipped (no device found)


So probably the problem comes from the GTX260 since it does not work alone. But if it would work, what would be the right settings to choose only device 2 and 3?

Thanks
Additional info... It seems like diminishing the n to 1 or removing both the -d and -n will sometimes make it works. Most of the time it will crash but sometimes it will start properly and crash at the very end.
