GPU PAGE FAULT in OpenCL kernel

Hi All,
               I am getting a GPU PAGE FAULT in OpenCL kernel in my OpenCL kernel while running on 8450 device.
               whenever I get a GPU PAGE FAULT, output of the kerenl is all 0s.
               The same kernel is working fine on 8550, and 8650 devices.

              in two cases the GPU PAGE FAULT does not occur
              1) when I add a printf() statement to the kernel.
              2) I have an array of 64 bytes in private memory (for each thread), when I define the array as local memory (for 256 threads)

              Will SDP can help me in anyway to analyse this issue?
              Is there any possible reason for this issue to occur?
