Hi! I am using a Curtiss Wright DY4-183 board with PPC7447 CPU. I've a pci graphics card with a M9 GPU on it. There is a transparent bridge between the GPU and my PCI bus. My problem a trouble with radeon_dri driver. I want to run a miniglx application to see how the graphics performance is but I am having the following error. I think there is a problem with unhandled interrupts! Have an idea?
