I still get these from time to time on several webservers, I have
reported it several times. It happens both whith and whithout secure-linux
patch (used in these ones). Strange is the slip_init_ctrl_dev in the
stack, no slip devices are used here. Stack garbage maby, but it is there
on all of them. It does not result in the machine crashing or so:
