Comment 0 for bug 1112652

I' ve this issue since kernel 3.8.0-1 (at the moment the 3.8.0-0 allows ethernet connection without any issue) :

if I plug in an ethernet cable, nothing appends ("cable unplugged" in network manager Gnome applet). If I put "on" instead of "auto" in the file :

/sys/devices/pci0000:00/<number of ethernet pci port>/power/control

then the ethernet connection begins immediately and succeeds.

Wifi works flawlessly in any 3.8 kernel.
