amd-gpu-pro update

[NoInstall]

I am almost there ...
I installed the fglrx drivers on ubuntu14.04.05 following atom's instructions.
It did not work if I compile the hashcat source code or use v3.20 however works (half works) on v3.10.
But on 3.10 it half works, as in if I can only use 1 of the 2 GPUs of the HD7990 card or it freezes/crashes ubuntu ???

For example this takes a few seconds to return the benchmark info and works:
************************************************************

./hashcat64.bin -b -m 2500 -d2
hashcat (v3.10) starting in benchmark-mode...

OpenCL Platform #1: Advanced Micro Devices, Inc.

- Device #1: Tahiti, skipped
- Device #2: Tahiti, 2101/3017 MB allocatable, 32MCU
- Device #3: AMD FX(tm)-8320 Eight-Core Processor, skipped

Hashtype: WPA/WPA2

Speed.Dev.#2.:   145.3 kH/s (95.25ms)




Or this also takes a few seconds to return the benchmark info and works:
************************************************************

./hashcat64.bin -b -m 2500 -d1
hashcat (v3.10) starting in benchmark-mode...

OpenCL Platform #1: Advanced Micro Devices, Inc.
================================================

- Device #2: Tahiti, skipped

Hashtype: WPA/WPA2

Speed.Dev.#1.:   145.3 kH/s (95.26ms)




But this does not work and freezes Ubuntu console and crashes after a few minutes:
************************************************************************
./hashcat64.bin -b -m 2500 -d1,2      OR   ./hashcat64.bin -b -m 2500

And judging from the temperature readings it is only loading the first GPU
