profiler - occupancy set only to 0 or 1, nothing in between

Has anyone encountered the strange profiler behavior - showing only 0 or 1 for occupancy? I tried OpenCL samples, for MatrixMul the occupancy is 1, for FDTD3d is occupancy 0.

Is there any reason for such output? How can I solve this issue?

I only saw a similar topic to mine, but without solution:-( http://forums.nvidia.com/index.php?showtopic=170280

Btw. testing on Ubuntu 10.04, GTX 275, driver 195.36.24, CUDA SDK 3.2 Beta
