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 ---------------------------- Jeroen Vreeken wrote: > Hi, > > This is a oneliner for 2.6 changing an unlock into a lock. > This prevents an oops on removal of the ax25 module. > > Jeroen de Bernard, f6bvp
