I have been working with catalyst 10.7 and SDK 2.5.

My system has APU (4 cores + GPU) plus a GPU on PCI. Before upgrading the kernel, I could see 2 GPUs and a CPU devices. After I can see only one GPU (PCI).

I upgraded the catalyst to 10.8 and reinstalled SDK 2.5. I can see only one GPU.

Please, let me know how I can debug the issue in more detail.

Thank you
