Running very stable. No other errors or so. Standard kernel config, only some old ISA cards removes and "device stf" appended. >Description: I wanted to use 6to4, so I've created a device stf0 with command "ifconfig stf0 create". Then... as I was bored, i though "let create device staff0". So, typed "ifconfig staff0 create". The system hangs. Nothing in logs, only reset possible. Then, after reboot, i tried to create gjiogjisdjgio device with "ifconfig gjiogjisdjgio create". Again, a hang. >How-To-Repeat: Type "ifconfig asshole0 create" or so... >Fix: Don't know how to fix, maybe first parse the device name and check it before doing anything? >Release-Note: >Audit-Trail: >Unformatted:
