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.
