I removed the second video card, reinstalled the ati drivers and it works now with clinfo and other tools working without segmentation faults. My only guess at the moment is that I may have a hardware problem with the 5850 which was causing the issues. $ ./john --list=opencl-devices Platform #0 name: AMD Accelerated Parallel Processing Platform version: OpenCL 1.2 AMD-APP (1016.4) Device #0 name: Barts Device vendor: Advanced Micro Devices, Inc.

If I need newer versions and an icd-registration program.. could someone point where I could get them? I have started a run to see how it works. X seems to become very non responsive when I do this which I figure is a good sign :). ./john --session=B --wordlist=wordlist00 --pot=john1.pot --format=md5crypt-opencl hash-md5crypt OpenCL platform 0: AMD Accelerated Parallel Processing, 2 device(s).
