All the boards i have either have an Ethernet Switch connected to the MAC, or a Micrel PHY. None are setup for WoL, since it is not used in the use case of these boards. I think you need to scatter some printk() in various places to confirm what is going on. Where is the WoL implemented: MAC or PHY, what is suspended or not, etc. Andrew
