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?
