What exactly does "The EEPROM Checksum Is Not Valid"? indicate?

I have three cheapo SuperMicro 1U servers (sm5013ct) which come
up with em0/em1 for the motherboard nics:

  em0 at pci1 dev 10 function 0 "Intel PRO/1000MT (82541EI)"
    rev 0x00: irq 10, address: 00:30:48:73:38:c6
  em1 at pci1 dev 11 function 0 "Intel PRO/1000MT (82541EI)"
    rev 0x00: irq 5, address: 00:30:48:73:38:c7


One of them will every three or four days drop the network and cough
up this message when you do a netstart. A reboot doesn't fix it but
a cold start usually will. The other two boxes have had no problems.
There are several messages in the archives relating to this including
one which suggests flashing the EEPROM using a SuperMicro utility,
which I have yet to try. I tracked it all the way to sys/dev/pci/if_em.c
but I'm afraid I've exhausted my capabilities at that point.

For now the bad box is the test box but I'm still curious...
