It seems to hibernate (suspend) successfully. If I omit that step I must setup
a wakealarm to trigger the wakeup, but that's it.

I attached the dmesg; I didn't reboot the system in between.


# history
   0 echo "module usbcore +mfp" > /sys/kernel/debug/dynamic_debug/control
   1 swapoff -a
   2 echo suspend > /sys/power/disk
   3 echo disk > /sys/power/state
   4 dmesg > usb.dmesg
   5 history
   6 grep URB /sys/kernel/debug/dynamic_debug/control
   7 grep "URB allocated" /sys/kernel/debug/dynamic_debug/control
   8 swapon -a
   9 echo +60 > /sys/class/rtc/rtc0/wakealarm
  10 echo disk > /sys/power/state
  11 dmesg > usb.dmesg


Thanks
