Sorry, none from my side. The last commit to the NCR driver in stable has been on December, 12, 1998, and it just made MAX_START (the number of commands active at a time for this controller) to a constant 32. Even with 7 drives and 4 tags each you are not going to hit that limit, and of course not from within the mount when going multi-user ... There have been a few changes in FreeBSD recently, and one of them may hurt you. Perhaps you've got LKMs that are no longer compatible with a recent kernel ?
