Bernd, I have an identical AS4100 at home (my office heater) and had put 5.4 on it last week. It also shows to be using a dc driver, the same DE500 card. Well, I think I've screwed my home server up this morning. It's connected to a Linksys 10/100 switch, and it had been running fine under 10baseT/half. I decided to try and switch it to 100, through a telnet session (should have not been a problem) and the card has locked up. I tried to set the card (now from the console) to auto-negiotiate, but nothing. No lights at all on the card. I've unplugged switch, card, power down, rebooted, but my network card is dead. It still shows succesfully probed in the dmesg, showing the mac address and all, but it's interface is DOWN and won't come back online or show any LED's. Having to leave for work after this fine piece of experimentation, I unplugged everything, turned power off on the server and left. Any ideas how I might rescue/reset my card? What are some options?
