What revision of the CPU do you have?? I know that upto rev C half duplex
has a problem with the cpu and only REV C silicon works if I am not
mistaken, there is an errata on IBM's website about this

Wow, I really had to spend some time to find such ancient hw :). I'll
try 2.4.27 with this hub during next couple of days (I'm a little busy
right now) and let you know. I suspect nobody really tested EMAC driver
in 10Mb HDX mode.
