Yeah I think I have an idea of what the basic problems are, but I'd have to understand things better before I know if I am really on the right track.

If your simple fix works though, then that sounds good. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
