HI,

We've run into a bit of an odd problem and we are not sure where to go and 
look for the cause.

We have some 440EPx based hardware with two GIG-Ethernet ports using RGMII 
and 2x ET1011C PHY's. Problem is that eth1 will only initialise correctly 
(i.e. receive and transmit) if eth0 has a link. Eth0 always work OK, 
regardless of eth1 status. Eth1 will work OK if eth0 has a link (i.e. 
initialised) at time of setup. Once initialised, eth0 status is irrelevant. 
All this is during Linux boot process.

Any ideas?

We can access PHY registers via u-boot (mii commands). Same 1Gig link speed 
is used on both ports. Linux kernel is 2.6.19.

Regards
   Jan Reyneke
