The main problem is that the cards are registering with the OS (Ubuntu server 16.04), but not with Hashcat.
We noticed this issue last Friday when we were running tests. We had 4 cards successfully running, drivers are all good. We saw the output, we had 4 cards. Then we started noticing that the output had changed and we only saw three cards functioning. We decided to restart the box, when it came back up we ran "lspci | grep VGA" and we got 4 cards. However, when we run Hashcat -b(or any operation, -b is just a faster test), the operation hangs and we simply cannot kill the process no matter how elevated we are.
If you have any questions, feel free to ask. I am fully aware that these card just might be fried, but I just want to know what else can be done. I just find it weird that the OS knows there is a card and registers it correctly but Hashcat won't anymore.
