I have the same problem. CPU i5-3230M on ivy bridge and OpenCL 1.2. I tried with 6.1.1 and 6.1.1+200.
Gpu is HD4000 and is not compatibile with hashcat. System Windows 7x64 SP1.
Didn't pass Initializing backend runtime for device #X ...
CPU is hogged at 25% (one thread busy) all time.
I tried on other machine with i7 of newer generation and AMD GPU and setting -D 1 -d 1 took this machine to start computing on CPU from "Initializing backend runtime for device #X" in less than minute.
