Commit 42eca2302146fed51335b95128e949ee6f54478f (in 3.8)
"PCI: Don't touch card regs after runtime suspend D3"
has changed behaviour of PCI PM core code a little. As result it has broken
power management in ethernet driver 'e1000e'. For example these devices cannot
detect carrier signal after connecting the cable if they are in deep sleep
state.
Tóth Attila has tested these patches for 3.8.y.
