Dell PowerEdge 1600SC Server: First it had Fedora 12 with Amahi Home Server on it, then I installed Windows Server 2003 Standard on top of it. The ethernet port worked for Fedora and Server 2003, but after a while, the port became non-functional - refusing to recognize ethernet cables...It simply regularly blinks a green light, whether a cable is plugged in or not. I tested the cables on working connections and they work.
I then decided to go back to Fedora 12, so installed that again. It still doesn't work...I've tinkered with settings in the BIOS, and the port recognizes the cable but doesn't provide LAN or Internet, only when the NIC is disabled and the IRQ set to a certain setting. I've tried running
cat /proc/interrupts in Fedora and choosing a IRQ that is not taken.
Can anyone tell me what is going on? How can I fix this?
