ML403 hard Ethernet under Linux 2.6.18

[Magnus Hjorth <mh@omnisys.se>]

Hi,

I'm trying to get Linux 2.6.18.6 working on an ML403 board with a basic 
EDK design with a hard_temac and uart. I've generated the BSP for 
linux_2_6, copied the drivers and twiddled a little to make it all compile.

The TEMAC driver seems to find the hardware, but the speed negotiation 
seems not to work. I can see the speed LEDs first go to 100 Mbit, then 
100 MBit again, and then 10 MBit. Since it's connected to a 10/100 
switch, the speed negotiation actually looks like it's working. Could 
anyone give me a clue to what's wrong? I would be thankful for any advice.

The output is given below:
