Out of curiosity, do only 3c509's exibit this behavior, or is this the core problem with 3c59x's as well? My experiences have not been consistent with these cards, and I had assumed it was due to buggy code in the 3-Com chipset. I've noticed flaky behavior from the "Vortex" [3c59x] card as well. Just now I have been wrestling with an ISA 3c509 which has a Lucent 40-01304 chip on it. At first the card was detected, and later not detected [on a different OS.] I vote for the fxp's as well, I've had hardly any problems with them. Is there a way to lock down the card by hacking the driver, so it won't try to auto-negotiate the connection?
