Ok. The ground reason of all that is this:
shutdown_kbdfront: error changing state device/vkbd/0/state to 5: ENOENT
The MiniOS kbdfront driver can not stop the backend because xenstore
doesn't let it set the state to closing. I fail to understand how the
ENOENT error could happen (but not for the fb part!), and don't really
have the time to investigate further inside the meandres of xenstore...
