I would happily try another ethernet card if that would solve the problem. But somehow, since I've tried a few cards ( i admit they are the same model, but one was a fresh new out-of-the-box card), I don't think another ethernet card it the solution.
The strangest thing is that it auto falls back RIGHT when the networking code in debian loads up, not when the box boots, not when the kernel loads the realtek code, but exactly when debian loads up networking stuff. Now why would that be? Could anything there cause this?
