I agree that it makes little sense on the surface. I did follow Jeremy's advice and enable AHCI in the BIOS. Even without loding the ACHI module at boot, that still solved the problem. (I also did load AHCI and it worked fine, which the DVD being recognized as a scsi/atapi-style cd0.) I'll turn of AHCI again and try to get a serial port hooked up so that I can do a boot -v and generate the panic (usually a little bit of disk activity will cause a panic). I'll send that in a separate email to you directly. thanks, michael
