Please try to run 'mii-diag -p 24' in these cases and teel us if it works.

I can't perform the ping right now as the switch and the computers are
both loaded. But I have done this in the past (sometimes up to 1 day for
testing) and I'm sure that I didn't get lost packets.

Output from 'mii-diag -v':

mii-diag.c:v2.00 4/19/2000 Donald Becker (becker@scyld.com)
 http://www.scyld.com/diag/index.html Using the default interface 'eth0'.
 MII PHY #24 transceiver registers:
   3000 782d 0040 6176 05e1 41e1 0003 0000
   0000 0000 0000 0000 0000 0000 0000 0000
   1000 0300 0000 0000 0000 012e 0200 0000
   003f 853e 0f00 ff40 002f 0000 80a0 000b.
 Basic mode control register 0x3000: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
   This transceiver is capable of 100baseTx-FD 100baseTx 10baseT-FD
10baseT.
   Able to perform Auto-negotiation, negotiation complete.
 Your link partner advertised 41e1: 100baseTx-FD 100baseTx 10baseT-FD 10baseT.

As you can see, my switch doesn't advertise flow-control (41e1 instead
of 45e1).
