The broad based issue is that on two manufacturers Ivybridge plus an Intel SDP Ivybridge, xHCI will not wake up from D3 when a USB device is plugged in. > > > In > > other words the issues you are having is that the MSI after resume are > > not delivered - but some are ? > > Only D3 wake ups (ACPI and PME) are not being delivered. If I change the runtime power policy for the device from "auto" to "on" xHCI works fine. >This indicates that xhci is not turned into a sources for wakeups because the device is already asleep and suspend() won''t be called twice. Does it work if you suspend with a device for which autosuspend isn''t on? Regards Oliver
