How else do you suggest that people figure out whether symptoms are
produced by the xhci-hcd driver or something else?  However, I agree
that it's not useful _any more_, since Mathieu tried that test
already.

Hm.  Mathieu, is it possible to suspend-to-disk ("echo disk >/sys/power/state")
and resume with a USB device plugged into the USB 3.0 port?

Please also attach output from "acpidump" after a successful boot.

Can you reproduce this when booting in recovery mode with
i915.modeset=0 appended to the kernel command line?

Thanks,
