    Hi,

    Is there any chance that you could have a look at rose.o module code in
    order to fix a kernel panic problem.
    If rose module is just installed it can be removed and reinstalled
    without problem.
    But as soon as I do "ifconfig rose0 2080175502" I have a kernel panic.
    Also if I perform a rsattach and try to remove the module then I have a
    kernel oops.

    Once I had the chance to catch this message from syslog@f6bvp
       (f6bvp is the actual name of my Linux machine):

    f6bvp kernel : unregister_net_device : wainting for rose0 to become
    free. Usage count =1
    repeats x times ...

    and then I observed a catastrophic PC reboot.

    73 de Bernard, f6bvp
