Hello!
I'm using Linux Mint 17.1 Cinnamon with an AMD Radeon HD 6950, driver version 14.6 beta 1, using oclHashcat64 version 1.37 and I'm trying to decrypt some phpass hashes but my computer freezes when doing it and I need to reset it to get it back working.
No input from keyboard or mouse works, but what's odd is that I can SSH to the computer when it's frozen. Although nothing seems to get it up and running again except for the resetting it physically. I'm fairly new to Linux/hashes so please let me know what kind of information I should provide or to try.
These are the different parameters I've tried:
Code:
oclHashcat64.bin
./oclHashcat64.bin -m 400 -a 0 -w 3 --username --gpu-temp-disable -r rules/InsidePro-PasswordsPro.rule ifkhashes /usr/share/wordlists/ifkultimate2.txt
Freezes after a minute or so on clean install
./oclHashcat32.bin -m 400 -a 0 -w 3 --username --gpu-temp-disable -r rules/InsidePro-PasswordsPro.rule ifkhashes /usr/share/wordlists/ifkultimate2.txt
Freezes instantly
./oclHashcat64.bin -m 400 -a 0 -w 3 --username --gpu-temp-disable ifkhashes /usr/share/wordlists/ifkultimate2.txt -o ifkcracked
took 2 seconds, no freeze.
./oclHashcat64.bin -m 400 -a 0 -w 3 --username --gpu-temp-disable ifkhashes /media/unknownpwn/Backups/wordlists/Super-WPA -o ifkcracked
Froze after caching the wordlist
./oclHashcat64.bin -m 400 -a 0 -w 2 --username --restore-disable --gpu-temp-disable ifkhashes /media/unknownpwn/Backups/wordlists/Super-WPA -o ifkcracked
Froze after caching the wordlist
cat /usr/share/wordlists/ifkultimate2.txt | ./oclHashcat64.bin -m 400 ifkhashes --restore-disable --username
Took 2 seconds, no freeze.
cat /usr/share/wordlists/ifkultimate2.txt | ./oclHashcat64.bin -m 400 ifkhashes --restore-disable --username -r rules/InsidePro-PasswordsPro.rule
Freezes instantly
cat ifkultimate2.txt | ./oclHashcat64.bin -m 400 phpasshashes --force -r rules/best64.rule
Removed drivers and installed beta drivers instead, downloaded oclHashcat again and tried with clean working directory. Took 2 seconds, no freeze
cat ifkultimate2.txt | ./oclHashcat64.bin -m 400 phpasshashes --force -r rules/InsidePro-PasswordsPro.rule
Froze instantly
I've tried several versions of the graphic card driver, currently running the latest beta drivers from AMD ( linux-amd-catalyst-14.6-beta-v1.0-jul11 )

I've found no logs in /var/log/ that can point me in the right direction.
If anyone can assist me I'd be grateful.
Thank you
