It seems there's some confusion, so let me clarify:

The patch in #16 should fix the following case: shutdown with the xhci_hcd module loaded.

It will not fix the case where xhci_hcd is unloaded before the system is shutdown. However, we expect that most users won't unload the xHCI driver before shutting down their system, so this shouldn't be an issue.

Reporters, please try the patch mentioned in #16 against a vanilla 3.12 stable kernel, and shutdown with the xhci_hcd module *loaded* to see if it helps. Please update this sighting with whether the patch helped or not.

So far:

Giorgos reports reverting commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix spurious wakeups after S5 on Haswell" allows the system to shutdown without rebooting when the xhci_hcd module is loaded. He hasn't tried Takashi's to see if it helps, please do so.
