I have two other boards connected to each other by crossover. One side has AP level 5 for AP and the other has AP level 4 for bridge. All interfaces are bridged with a single IP on each board, but when I boot either one the entire board locks up and fails to reboot. We have to manually go and pull the plug on the power to the boards to get them to reboot. What could be wrong? Any suggestions on how to resolve this?
Please any help on this problem? It is starting to cost us customers 
What could cause lockup when rebooting?
