Okay, here's something to try. Boot with -v, and see if you get any tagged openings messages after you issue the 'camcontrol tags da0 -N 4' command. If you do, then for some reason the inquiry data for the RAID array is reporting that it can do tagged queueing, despite the fact that dmesg doesn't show it. If you don't see those messages, then I don't see how you're seeing more than one tag in the output of 'camcontrol tags da0 -v'.
