I have so far not been able to activate it properly and the lock is needed to protect from PCI and NOR i/o clashing with eachother. i know that the arbitor works when using lantiqs 2.6.28. i will provide a follow up patch once i figured how to bring up the arbitor properly. until that time we need to use the lock. thanks, John
