Is there something obvious that > I'm missing about how to fix this problem? Hi there. I am not sure if this is a 100% solution, but can you try using the find-sb utility. You can run this utility as root, once you have compiled it: # cd /usr/src/tools/tools/find-sb # make # ./find-sb <device-name: e.g. /dev/ad0> Hope that helps.
