We use SMC EtherPower (8432T) cards, and have seen similar messages: "de0:
enabling AUI port" when the card has only a RJ45(!) We have had problems
with the cards going to "sleep" spontaneously as well. We used to have to
ifconfig down and ifconfig up to get them to wake back up. Although when
we upgraded to 2.2.7, this fix no longer worked.
I've been asking around and it may have to do with the auto-sensing not
working quite right. You can explicity state the port to use (and thereby
disabling media auto-selection), via ifconfig:
ifconfig de0 media 10baseT/UTP mediaopt full-duplex
When you "ifconfig de0" you should see this:
media: autoselect (10baseT/UTP) status: active
change to:
media: 10baseT/UTP status: active
Also, I received a suggestion to "write a keepalive script for de0, which
seems to go to sleep more often than others".
