Unfortunately I don't have any proven-to-work-well previous kernel for this specific hardware config, and dmesg does not show anything even slightly usefull. However, I've just installed Debian Woody (kernel 2.2.20, gcc 2.95) and got something interesting. There are two interfaces shown in ifconfig: eth0 Link encap:Ethernet HWaddr 00:11:6B:32:85:74 inet addr:192.168.0.3 Bcast:192.168.0.255 Mask:255.255.255.0 ...... Interrupt:9 Base address:0x6000 eth1 Link encap:Ethernet HWaddr 00:11:6B:32:85:74 inet addr:192.168.0.4 Bcast:192.168.0.255 Mask:255.255.255.0 ...... Interrupt:9 Base address:0x8000 whereas actually only one physical network card present. One can notice HWaddr and Irq is the same, although base addr is not. lspci says: 00:0d.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139 (rev 10) Now as soon as ip configuration is done preperly, I can ifup any of them successfully. And, eth0 shows some familiar misbehaviour: I can do ssh, but scp large file fails with subsequent communication breakdown. On the other hand, eth1 works fine, scp and iperf3 (both as a client and as a server) show quite regular operation. I'm puzzled a bit. But at least it looks like a possible starting point.
