I have the latest kali linux with everything up to date. I have an amd graphics card which works and had no problems with until the recent updates and now it no long works with pyrit and oclhashcat. It keeps crashing.

A sample of the output i receive every time is as follows:

root@kali:~# pyrit benchmark
