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

[frnck]

OK so -m 22000 seems to be working for me with the latest beta, if I try with a known hash and a small dictionary. 
But when I go "-m 22000 -a 0 rockyou.txt  -r ./rockyou-30000.rule" hashcat seems to get stuck and become irresponsive after showing the "[s]tatus [p] (...) =>" line.
I can see the GPU load moving between 100% and some number using GPU caps viewer though.
Any idea?
