Description of problem: When I boot into 2.6.40 kernel (updated some days ago), my Wifi card gets an IP from my home router (a dd-wrt firmware), then the router stops responding after several seconds. Does not happen with a 2.6.38 kernel on my laptop, nor with the Windows 7 it has. Never happened to me with F14 of course or earlier F15 kernels. Version-Release number of selected component (if applicable): 2.6.40.3-0.fc15.x86_64 How reproducible: Always. Steps to Reproduce: 1. Boot with kernel 2.6.40, wait for an IP from my router. 2. Wait a few seconds (in which I actually have connectivity) 3. Boom - router's dead. A reboot is needed. Actual results: Expected results: Additional info:

This should be "fixed" in kernel-2.6.40.4-5
