Kernel:

[root@oboe log]# uname -a
Linux oboe.localdomain 3.11.1-200.fc19.x86_64 #1 SMP Sat Sep 14 15:04:51 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Apparently related to the alx kernel module

It is the same bug as reported here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1213009
https://bbs.archlinux.org/viewtopic.php?pid=1328254

It worked fine with kernel 3.10.x but fails with the new 3.11.x

As this is a showstopper, I need to go back to use kernel 3.10.x
