@rrete,
Not to suggest bad news, but I had a similar problem with a CV64. The guru 80000004 turned out to be bus errors. I tracked it down to read/write attempts in the Cybervision's address. It would crash or freeze the 3000 w/Piccasso 96 or Cybergraphx. I finally got a 4000 and tried it in that with the same results. And this was with superbuster 11 in both 3000 and 4000. Conclusion: the card was faulty. So if you do have a 4000, or even another 3000, give it a go in that Amiga. If you get the same or similar results, it's the card. Sorry.
