Rafael, > Does it also happen if you rmmod the xhci-hcd module manually and run > "echo disk > /sys/power/state" afterwards? yes. I do an rmmod xhci, lsmod | grep xhci returns nothing, and then echo disk > /sys/power/state will give me the same result as pm-hibernate. that is, I get to an empty screen, there's a cursor blinking on the top left. after a while, the screen dims, but nothing else happens. only a power cycle saves the day, where the machine boots normally, when just turned on. how could I debug these happenings further?
