Comment 250 for bug 1667750

After several tests, I assume that this warning:
"rt2x00queue_flush_queue: Warning - Queue 14 failed to flush"
is also related to the xhci issue. I don't think that the issue is related to powermanagement (https://bugzilla.kernel.org/show_bug.cgi?id=61621), because pwrmgt is disabled, here.
