There seems to be a conflict here, it seems as if a driver called
'8139cp' is being loaded before '8139too'.
One thing to try, shut down the network interfaces (/etc/init.d/network stop),
remove the 8139cp module and the 8139too modules:
rmmod 8139cp
rmmod 8139too
Re-insert the 8139too module:
modprobe 8139too
Start networking again:
/etc/init.d/networking start
Verify that the 8139cp driver is not loaded: lsmod | grep 8139cp
If 8139cp is loaded again try flat out moving the module out of
the /lib/modules/`uname -r`/ directory tree to another location,
and repeat the above.
and try your test again
