Hi,
After creating a powersave script based on PowerTOP Tunables, this particular line prevented the system from being able to shutdown (Asus Zenbook UX31E, kernels 3.0 - 3.1.2):
### Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 echo auto > /sys/bus/pci/devices/0000:00:1d.0/power/control
Kernel prints the "Power Down." message but machine doesn't power down.
Is this a known bug? Could this be fixed in the driver instead of:
echo on > /sys/bus/pci/devices/0000:00:1d.0/power/control
on system shutdown?
