I just tried to do a clean install of 8.10, after using 8.04 on my thinkpad t61p. It was a disaster. Not only did I have the GigE problem so no ethernet
but I also had the "Wireless event too big" problem with my ipw4965 card
So no internet connection at all!! I'm just doing a reinstall of 8.04.
My advice for owners of this laptop is to wait till the RC version appears and the bugs have been fixed
