OpenCl kernel self-test failed when using any version later than v4.2.1 !!

I would suggest that you at least try to run the beta version from https://hashcat.net/beta . It tries to work around many driver problems. This is the sad part of being dependent on working device drivers, each and every driver version could be different and introduce new problems (but also fix some) and that we generally get no attention/answer from any hardware vendor (atom already reported dozens of easy to reproduce OpenCL driver bugs, the chance of an answer, let alone a fix is very, very, very slim)
