So… Why? Adrian hinted that it has something to do with a name change, but I’m unable to figure out what that change could be??? If it is a bug, it’s a minor one, and it’s easily worked around by the addition to /etc/modules. But I’m curious to know what changed? If it is a name change, as Adrian suggests, I’m curious to know what changed and why it was changed… Thanks to everyone for all the good work! Rick
