I've got a Cisco 2900 at home that does the same thing. Oddly, it does
it to my laptop also (Linux with an Intel 10/100 card). Autosense fails,
and if the cable is plugged in at boot-time, I get no connection. I have
to boot the machine, let it come all the way up, then plug in the
ethernet, and I only get 10 half (this is all the laptop).

My SS2 never had a problem. SS20 comes up with no carrier at boot time.
Haven't got to the point where I'd know if I have net yet or not after

And I think it's the switch. At least in my case. Perhaps it's something
about the autonegotiation? I'm going to dig around Cisco's docs.
