Hi, Would you be willing to try a -HEAD snapshot on your laptop? Maybe I've fixed it as part of the other driver work that I've done as part of development in -HEAD. But right now I really have no idea. I don't have a T60 here that has that chip in it. If all the T60 BIOSes allow AR5418 NICs then I can try it out, but all of the T60's I've played with thus far have the intel hardware in it.
