Dual Port Ethernet not working on PE2550

The PowerEdge 2550 has an Embedded Intel Pro 100+ NIC (82559 Chipset) and
the Embedded Broadcom Gigabit NIC.  It does not have an on-board dual port
Intel Pro 100+ NIC.  Using either the eepro100 or e100 native module works
fine under Linux 7.1.  It could be a negotation issue between the on-board
NIC and your Cisco 29xx switch.  Either try another switch, port, or force
your negotation to 10Mbps or 100Mbps.  Also, one thing you may want to look
at is the cable that is plugged into the back of the Intel NIC on the
server, make sure that it is not loose and it has a good connection.

maybe the negotiation isn't working with your cisco switch? (35xx
and eepro communicating very well here).
 have you looked at the messages while loading the eth0/1 module? you
could also try eepro-diag from donald becker...

The card works fine when first powered on, but when warm-booted, both ports
on the ethernet card don't link up to the switch(cisco29xx).

to those ethernet ports until I power cycle.
