Package: src:linux Version: 3.11.5-1 Severity: grave Tags: patch Subject kind of says it all. My system freezes solidly as soon as I ifup the network interface. Please see e.g. http://www.spinics.net/lists/netdev/msg251287.html for more details.
Attached patch from mentioned URL fixes the problem for me. I haven't checked if kernel devs used the same patch, though. Michael
