OpenCL samples segmentation fault running on Fedora 12, quadro fx 570M


I’ve downloaded the NVIDIA driver, CUDA toolkit, and the SDK samples onto my thinkpad t61p (running fedora 12 with Quadro FX 570M graphic card). I was able to get the CUDA samples to compile and run fine, however, the OpenCL samples, all of them seem to seg fault at clGetPlatformInfo().

Could someone help me with this?
