Just chiming in to say that my issue as detailed in this photo ( http://i29.photobucket.com/albums/c276/saivert/kdl.jpg) had nothing to do with ATA/IDE controller driver issues. It was a glitch caused by a bad install of Haiku. I wiped the partition clean and did a fresh build (not using update-all as I previously used) and now I can reboot as many times as I want and I never see the KDL. I still wonder what file or data in caused this though. Guess I will never know.
