Correct, at the moment I'm using a USB3 enclosure with a JMicron ATA-USB bridge. However the same problem already occured with a different USB3 enclosure (ASMedia ATA-USB bridge). I don't have more USB3 device with me at the moment, but I know at least that it doesn't happen with the Logitech USB mouse (hence my guess that it's an issue with xhci_hcd). > The log doesn't include much useful information, partly because your > kernel was built with several debugging flags turned off and partly > because there is very little debugging info available for wakeup > events.

If you tell me which debugging options I should enable, then I can create more verbose logs. > Have you tried unloading or unbinding the xhci-hcd driver before > starting the second suspend? Not yet, going to give this a try later.
