Sounds oh so familiar.

Does it work if you run port 1 as "single port"?  Or only "port 0"?

We have had problems as soon as port 1 is used, on a specific hardware
revision on the PA-2FE-TXs.

We also saw hard crashes.

Bingo (this is "our problem child" in a 7500/VIP2-50):

        PA Bay 0 Information:
                Dual Port Fast Ethernet (RJ45), 2 ports, FRU: PA-2FE-TX=
                EEPROM format version 4
                HW rev 1.00, Board revision B0
                Serial number: JAE064006VR  Part number: 73-5419-06 

All reports seen here in this list that had issues with PA-2FE-TXs have 
HW rev 1.00 / board revision B0.

We swapped the faulty one in our 7200 to a PA-2FE-TX with revision C0,
and both ports are working perfectly well now...

It would be perfect if you could open a TAC case on this, so this could
finally be tracked down (we can't right now).
