Maybe give it a try and see if at least the warnings go away? The range warnings go away on the 4460 as well. The warning 'twl: not initialized' of course is still there. Still need add the patch for it again and test. Another effect I have noticed is that the system seems to be a little bit more 'stable' now. Which means it does get a little bit further before crashing. I even managed to get to the login prompt one time... >> There is a little patch around that changes the initialisation order which makes >> this messages go away but does not fix the odd behaviour.

Do you have some link for the patch and discussion?
