Small problem with the startup script in RedHat 7.0 for ISDN.
It starts the ipppX device (ifconfig ipppX up) before the isdn provider is
fully configured if you have an bundled config. This causes isdnctrl to
reject the slave interface.
Solution is maybe to move the activation of the interface to last thing in
It's fixed. you should download internet-config-0.22 in the rawhide.
Note: internet-config is a replacement of isdn-config and adsl-config.
