Like I said, here are my findings: Jeremy's pointers were very correct, the difference in numbering seems to be just an ata(4) change. Manually changing entries in /etc/fstab does fix it, and I found out that the kernel panic I was getting was merely a simple detail I overlooked: The 3rd-party nvidia driver had been compiled on -RELEASE and was causing the kernel panics on -STABLE. Simply disabling its loading at the boot loader prompt, then booting with /etc/fstab properly updated and then reinstalling the nvidia-driver port (`portmaster nvidia-driver`) fixed it. Just to be on the safe side, I also reinstalled the other 3rd-party kernel module I use (fusefs-ntfs3g), even though it wasn't giving me any errors. I did try the -STABLE snapshot image as Jeremy suggested, that's how I figured he was right about the numering difference being an ata(4) change. I preferred to just manually change the previous install's /etc/fstab, though (but maybe there was a better way of doing this with the -STABLE snapshot DVD). The interrupt storm on irq21 is still happening, and I'm going to work on that next. Mounting any non-audio CD/DVD stops it, so I'll keep doing that until I actually find a fix for the issue. So thank you very much, Jeremy. Your pointers were very helpful in fixing my problem. Best regards, Fred
