I have almost the exact same setup (A3000/CyberstormPPC, CybervisionPPC, 96MB on CS, 16MB Fast on m/b). I use a Quantum 700MB SCSI2 drive and 2X NEC SCSI CDROM on the native controller and a 18GB Seagate Cheetah SCSI3 Ultra on the CS's controller. I also use AsimCDFSv3.10 and have successfully installed OS3.9 (but not the BoingBags). The only problem I have is that one of the partitions on the Cheetah drive is not initialized on warm reset. I have to do a long warm reset (hold down Ctrl-Amiga-Amiga 10 secs) or cold boot. I don't remember exactly but I think I had trouble with the BoingBags (probably the ROM update was the problem). I think there is a timing problem between the A3000 native SCSI controller and the Cyberstorm's. I did operate my machine for a few years without the motherboard battery, so maybe I screwed up the NVRAM SCSI settings. Seems to run okay now (I'm typing this on it).
