Changeset 31028 - update linux 3.2 to 3.2.12 <- this causes the problem. The switch is no longer works in my machine. swconfig can still see that a link is up or down, but that's it. Changeset 31026 may cause part of the issue too. Prior to 31026, I get the following in my logs on boot: kern.info kernel: [ 0.660000] ag71xx_mdio: probed kern.info kernel: [ 0.660000] eth0: Atheros AG71xx at 0xb9000000, irq 4 kern.info kernel: [ 1.240000] eth0: AR8316 switch driver attached. kern.info kernel: [ 1.240000] ar8316: Using port 4 as switch port kern.info kernel: [ 1.340000] ag71xx ag71xx.0: eth0: connected to PHY at ag71xx-mdio.0:00 [uid=004dd041, driver=Atheros AR8216/AR8236/AR8316] from 31026, I no longer get that information in the logs. I haven't had a chance to stress test it yet, so I'm not sure if there are any implications with the change. -Greg
