Undoubtedly this change in behavior is caused by the "autostop" code I added to ohci-hcd. It doesn't check the "wakeup" attribute. Dave, is there any clue about exactly what triggers the immediate wakeup? If you could tell me what to test for, I could try writing a patch to fix it. Perhaps the driver needs a "resume_detect_is_broken" quirk. Andrey, if you aren't using USB at all (you mentioned that no devices were plugged in), you can simply do "rmmod ohci-hcd" to stop all those log messages.
