Problematic Realtek RTL8111B

[Adesso]

Greetings.

After going trough alot of the forum I figured that my Realtek RTL8111B onboard card has some issues, but it seems mine is a bit more than just not working. I managed to get the card working with FC7 (Lucky) but only for a while.. and then it dies..

I shut her down.... wait a while and when I boot back up .. she is working again, but trying a update just takes to long, as it dies halfway through the update.. I managed to get a kernel update done once.. so I think I am running the latest kernel, but can't seem to get this network card stable..

Should I take this mainboard back and tell them it is faulty? Is there a program that I can use to prove my point ?

I regrettably bought a ASRock ConRoe945G-DVI board, my first and definitely last ASRock board ever...

Any suggestions.. ?

AsRock might be a affiliate of ASUS, but that does not mean anything... IMHO they suck

After a surprise read in the CT magazine, it seems that this Network card has some special feature that switches it off at hardware level.. ??? The magazine mentioned a Windows driver that switches it off so that Linux can not switch it on again, and that enabling the Wake on LAN in windows would solve the issue.. but I am not installing windows just to switch on the LAN card.. this is silly..

The cards involved are apparently the RTL8168B / 8111B chips that are on some Motherboards... really weird.. I guess this is part of my problem. Maybe the driver used by Linux somehow switch it off by accedent after a while.. and then you are screwed ..

Anybody heard something like this before .. ?

In the meantime I have slotted in a Old 3COM Network card, and disabled the onboard chip till I can find a solution ..
