Try using hard_temac_v3_00_a with the ML403 board. There's an
incompatibility (posted previously on this list) with PHY access. This
could be causing the strange behavior you're seeing.

Subject: Problems with plb_temac+hard_temac+2.6.24rc3
Hi,
I am working with a ML403 platform and I have my kernel 2.6.24rc3
perfectly running on it. Almost everything seems to work but the
ethernet. I am using the IP cores that come with the EDK 9.1sp2 (
plb_emac 3.00a + hard_temac 3.00b). The weird thing arises when I try to
bring up the interface and use it. If I do "ifconfig eth0 up" the
interface shows up but, strangely, it eithers not receives or send
packets. I will explain myself, if I assing an IP manually and try to
connect to another worksatation within the network ( by pinging from
just one of the sides for example ) the interface seems only to send or
receive packets , but generallty not both at the same time ( I can see
this through the evolution of the Rx/Tx bytes in ifconfig). The only few
times that both tx/rx work at the same time is when I do (ifconfig eth0
down and ifconfig eth0 up), but this only works sporadically and only
for around a second or less.
This is what I get after the first "ifconfig eth0 up":
[ 293.258765] eth0: XTemac: Options: 0xb8f2
[ 295.253048] eth0: XTemac: speed set to 10Mb/s

[ 297.252047] eth0: XTemac: PHY Link carrier lost.
[ 299.251657] eth0: XTemac: PHY Link carrier restored.
and this after some ifconfig up/down:

[ 1184.018815] eth0: XTemac: PHY Link carrier lost.
It also seems to negotiate wrongly the speed since my network is
100Mb/s.
This is my dmesg before "ifconfig eth0 up":
