There have been changes over time of the MII link management 
code used by Anaconda.  I encounter these issues with 3-com 
nic's and Intel switches, but have also encountered them with 
T-Lan nic's as well.

Simplify the network topology - go to a straight crossover to 
your dhcp/next server if possible - alternatively, consider 
trying a single switch between the unit under test and the 
dhcp/next server -- then vary the switch brand, to test each. 
If possible, run TCPDUMP on the server side, and see whenre 
the connection is failing.
