Version-Release number of selected component (if applicable): kernel-2.4.21-27.EL How reproducible: Always Steps to Reproduce: 1. Just boot it... Additional info:
It seems like the NIC starts to work again if one unplugs the laptop from the power outlet and removes the battery for a little while. And then the NIC works until someone boots it with MicroSoft Windows. After running windows on the laptop you have to do this kind of hard reset again, removing the power alltogether to get it to work.
