From: Bjorn Helgaas <bhelg...@google.com> Dexuan, the important thing here is the first patch, which is your [1], which I modified by doing pci_restore_state() as well as setting to D0:
pci_set_power_state(pci_dev, PCI_D0); pci_restore_state(pci_dev); I'm proposing some more patches on top. None are relevant to the problem you're solving; they're just minor doc and other updates in the same area. Rafael, if you have a chance to look at these, I'd appreciate it. I tried to make the doc match the code, but I'm no PM expert.
