I don't know what this is doing on -current but anyway....

You don't say what has changed on the machine.  Is this a new install?
At some point between FreeBSD 2.2 and 4.6 (don't ask) I could install
from the CD but not boot off the RAID disk later.  Changing a DAC960
BIOS option from 2GB to 8GB made it boot.

That looks like the mundane kernel/world out of sync.

One suggestion based on your dmesg...

Have you disabled the bios on your Adaptec SCSI Adapter?  If not, it may
be loading before the DAC960 bios and only be looking for a bootable
disk on that controller.
