I think I have the same problem with my Amiga4000. I have asked here often, but no answers.
It seems that my computer hang whenever I try to run the CBvision-driver (I moved it out of drivers/monitors just to see if this was the trouble).
Ive also tried with anotoher card, RetinaBLTZ3 with the same result. So i'm fearing my 4000 got some seroius hw-problems.
And dont tell me to format and junk around with p96, cause Iv'e tried that. Installed a dozzen of times, and it has worked. I had my miggy cabbed for a rather long time, I'm guessing some static cat went by and flashed my dear miggy.
It works whenever I dont run any graphicscard in it.
But, an advice could be just to move the CBVison3d-driver out of drivers/monitors, reboot and see if it hangs then (on aga, that is) and then launch the driver by hand. Not that it helped me, but...
