May also be a corner case of a JOCL bug w/ that specific driver.
If float data CPU <-> GPU/CL-Kernel works properly on that device
and/or the others it simply seems to be a driver bug.
The float data transfer seems to work fine w/ you setup,
since casting the value works for you.
Another idea .. maybe it's related to the different OpenCL version ?
Just brainstorming ..
