I seem to have identified a side effect of doing this. It breaks ethtool. I need to force my ethernet interface to on in order for ethtool to return information:
I wonder if this is a kernel bug.Code:echo "on" > /sys/devices/pci0000:00/0000:00:19.0/power/control
By the way, Wake On LAN seems to be enabled on my laptop. Since it will never need that feature, I turned it off via "ethtool -s eth0 wol d".
