Yeah, I'm reasonably sure (based on my own testing on internal, PCIe plugin and expresscard) that the NEC chips are just busted in this respect. Either that or theres a magic "Make things work" bit, but given Windows doesn't appear to use runtime PCI PM that may be optimistic. What I'm hoping for here is to just work out why your ehci wakes up as well - it's not damaging, but it is messy and does suggest there's something wrong. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
