I just booted a 2.6.10rc3 kernel on my SWARM and noticed that only eth0 is configured, but eth1 isn't (even though I booted via eth1): sbmac: configuring MAC at 10064000 eth0: enabling TCP rcv checksum eth0: SiByte Ethernet at 0x10064000, address: 00:02:4C:FE:0D:08 sbmac: not configuring MAC at 10066000 On a 2.4.x kernel, both network interfaces are configured and I get: eth0: SiByte Ethernet at 0x10064000, address: 00-02-4C-FE-0D-08 eth0: enabling TCP rcv checksum eth1: SiByte Ethernet at 0x10065000, address: 00-02-4C-FE-0D-09 eth1: enabling TCP rcv checksum Note the difference for eth1 between 10066000 (2.6) and 10065000 (2.4). Thiemo suggested that this might be because the 2.4 kernel is 32 bit while the 2.6 kernel is 64 bit and that 2.6 might get the address wrong. -- Martin Michlmayr http://www.cyrius.com/
