I can trivially reproduce this on two different machines. I choose Hibernate from my Gnome desktop and after a few seconds the screen switches to text mode. If I do nothing there is just a flashing cursor for about 15 seconds, then disk activity starts and then the machine powers off. (My machines have about 150 processes and 6-8GB of RAM).
If I disconnect the USB device during the 15 seconds then this error occurs. It is most common with my USB keyboard and mouse. The kernel spends quite a while whining about it before giving up on the hibernation. My best guess is that whatever hotplug infrastructure is needed in user space (and possibly kernel space) has been frozen. See the attached file with relevant dmesg excerpt. ** Attachment added: "log" http://launchpadlibrarian.net/38984666/log -- hibernation poweroff fails when disconnecting USB: "cannot enable port 1.
