Hi, 

The output of lspci -v for the GBE is:
 
========================================================

Gigabit Ethernet Controller (Copper) (rev 01)
        Subsystem: Intel Corp. PRO/1000 MT Dual Port
Server Adapter
        Flags: bus master, 66Mhz, medium devsel,
latency 32, IRQ 14
        Memory at f6020000 (64-bit, non-prefetchable)

        I/O ports at dc40 [size=64]

Further, I reverted to 2.4.20-8  , and still no
improvement ! The target side has 2.4.21.
