Dual GPU & OPenCL/Mesa Issues - DrRobotnik - 02-16-2017
Hi,
apologies if this is in the wrong subforum.
I recently posted here for some advice on my previous GPU (https://hashcat.net/forum/thread-6265.html) and after banging my head against a wall, decided to bite the bullet and invest in a better GPU that was compatible with the AMD-GPU-pro driver (why i didnt just go for NVidia then, i dont know, i hate myself)
Purchased a AMD R9 290x, and after again banging my head trying to get the AMDGPU-pro driver installed on The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) with 4.9.6 kernel (its wouldnt install the module against that kernel version, only 4.4) i managed to get this GPU running on hashcat on Mint 18 with a 4.4 kernel.
Great! so i bought a second GPU, another R9 290x. Plug and play i think.
However this is where i encountered the problems. The PC recognizes both cards, and can benchmark both at around 190K each for WPA. But when actually cracking, i get the following errors:
Code:

Looking at the messaging, it would appear that OpenCL version 1.1 is not compatible, but this is what was installed with the AMDGPU-pro driver. I dont think my hardware is at fault as both were able to benchmark successfully together and if both run when cracking (at times seperately) i dont think its the hardware.
Really stumped as to why these dont work together, and cannot seem to upgrade OpenCL to 1.2 or 2.0 if compatible (cards are compatible with 2.0 after reading the wiki) or if this would even fix the issue.
Any advice would be greatly appreciated.
Thanks

Get rid of Mesa.

How? Removing mesa-opencl-icd automatically removed hashcat. And reinstalling hashcat reinstalls mesa?
Is there a version of hashcat that runs without mesa, or a way to remove mesa without uninstalling hashcat?
RE: Dual GPU & OPenCL/Mesa Issues - epixoip - 02-18-2017
Get rid of The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali). Or stop installing hashcat via The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali)'s repository. Or run Hashcat with --opencl-platforms 1 to only use the AMD platform. Or do all three. Either way, Mesa is the issue here. And if The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) installs Mesa along with hashcat, then The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) is the issue as well.
RE: Dual GPU & OPenCL/Mesa Issues - DrRobotnik - 02-18-2017
Thanks for the advice. Wasnt aware that hashcat via the The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) repo would be the cause.
Have reinstalled hashcat from source on Mint, and am no longer seeing the previous errors with OpenCL/Mesa.
However, still only one GPU is being utilized (the below is a test cap to confirm both GPUs are working together):

Any advice?

Report the bug to Mesa. There's probably nothing that can be done.
RE: Dual GPU & OPenCL/Mesa Issues - epixoip - 02-19-2017
The pipe may be the culprit here. Can you test with other attack modes to see if it is?
