I've also run into it with ethernet connections under Windows. I've also run into it with Cisco-to-Cisco gear. For example if you dig around on Cisco conneciton online, you will find a known bug about connecting Cisco 2800's to Cisco 2950 switches - Cisco had to come out with a firmware update for the 2950 after releasing the 2800 due to ethernet chip incompatabilities. The smart-aleck answer is like the old "Doctor it hurts when I do this" "well don't do that" but it is also the right answer. Don't use a crossover cable in this application. I know it looks weird when you have a $7.95 hub you got from Goodwill that is plugged in between a $3K Catalyst switch and a $5K 2800 but when the customer won't pay for service on the switch to get the latest firmware for it, that's what you have to do to keep things running for them. I did leave the Goodwill price tag prominently on the hub, by the way.
