Try running this command in loader before starting the kernel: set hw.ata.atapi_dma=0 (or at least check that you aren't setting it to 1 in /boot/loader.conf) If that fixes it, then something is corrupting DMA transactions to your DVD drive. Check the cabling, try rearranging your ATA chains so it isn't a master device, etc. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
