The simple fix is to physically unplug and replug the cable. When it is not working (each reboot) there are not lights on. The physical "bounce" lights up the LEDs and it comes right up.
When you boot the system and get to the kernel selection menu can you stop the process by moving the cursor to a different kernel or by using "e" to edit the selected kernel? No drivers will be loaded at that point.
At that stage, so you see any LED's light or blink on the interface?
If "no", does that change if you unplug/plug the cable?
I use a wifi adapter for my main/Internet connection. This port is just used for a wired link to my Raspberry Pi.
Is it directly connected to the Pi?
