that just means that the device didn't get added for some reason. Nothing
that should affect the working of the server (other than that you obviously
can't use this device). If you ssh in before, you'll probably notice that
this line is already in the log while you're logging in. from your last
backtrace, it's the graphics driver that hangs.
