The surprising bit is that you manage to get any packets through at all. Ethernet packets don't have a TTL field, so if they end up in a loop (for example br0 -> eth0 -> LAN -> eth1 -> br0 -> ...) they just keep getting repeated. brctl br0 stp on should fix your network. I suspect you're trying to do bonding though, which (as far as I know, having never played with it myself) is configured completely differently and might require support from the switch.
