Could you also please try with the 3c59x driver which comes with the 
kernel (still running in "noapic" mode) ? It doesn't have the improved 
"polling mode" Tx path that Scyld's driver has, but it should be stable 
nontheless.

I'm sorry, I don't have the time; yesterday I was able to find an 
afternoon to look over code and docs for the EEPROM problem, but that was 
a very rare exception...

Maurice had problems with the board even with Windows. OTOH Don's 
experience is a good one; also I seem to remember that on the beowulf list 
several people said that they are using this board, however there was no 
complaint about network adapters...
