I don't think it really means much because if it's all host DMA memory outside of the range the lnc device can access, then it will look perfectly initialized like the driver expects it to -- because it is pristine! What I would do would really quick change the driver so that where there's BUS_SPACE_MAXADDR_24BIT, you replace it with a TUNABLE and then try out some different maximum values via the loader. I bet you'll find it stops working if you make it too big, and starts working if you make it small enough. -- Brian Fundakowski Feldman \'[ FreeBSD ]''''''''''\ <> green@FreeBSD.org \ The Power to Serve! \ Opinions expressed are my own. \,,,,,,,,,,,,,,,,,,,,,,\
