*** Bug 997217 has been marked as a duplicate of this bug. ***
Here is a scratch build with Sujith's patch included. Please test and let us know if it works. http://koji.fedoraproject.org/koji/taskinfo?taskID=5841387
Whoops, I unintentionally cleared the needinfo flag when I adding myself as a CC; sorry about that. :P FYI: same thing happened to me a few nights ago, on 3.10.10-200.fc19.x86_64, and I'm still seeing frequent (unreported) NIC lockups on 3.10.11-200.fc19.x86_64. Also, the koji scratch builds referenced above seem to have been cleared out at this point, so I can't actually try that build. :)
The patch referenced was included in the 3.11.1 stable kernel with commit 19c361608ce3e73f352e323262f7e0a8264be3af. It should be fixed in 3.11.1.
