Description of problem:
After installation of Redhat 9 I have created a dialup internet connection using
the Internet connection wizard or the Network configuration tool. The device I
use is the Fritz ISDN PCMCIA A1 card on a Compaq Evo N910 laptop. 

I can browse the internet (i.e., I can activate the network connection).
I can hang up the connection afterwards.

However, the computer hangs during shutdown when PCMCIA or ISDN services are
being stopped.

The same happens if you run >>cardctl eject<< on the command line or if you stop
either the PCMCIA or the ISDN service using the Services tool

It does not matter whether or not you hang up the connection before trying
either of the steps above - in either case the system becomes un-responsive.

Version-Release number of selected component (if applicable):
kernel-2.4.20-18.9 and 2.4.20-19.9 

How reproducible:

Steps to Reproduce:
1. Install Redhat Linux 9 (Lite Edition from the RedHat Magazine)
2. Plugin a Fritz ISDN PCMCIA card (A1)
3. Create a network connection (dialup)
4. Dial up the connection.
OBSERVE: Everything works fine - you can browse the internet.
5.1 Hang up the connection or let it run and shut down the machine 
OBSERVE: System hangs as soon as either ISDN or PCMCIA service is stopped.
5.2 Try to unload the card using cardctl eject or the redhat-config-services tool
OBSERVE: System becomes unresponsive as well.    

Actual Results:  System hangs and becomes unresponsive

Expected Results:  System should not hang but cardmgr should gracefully exit the

Additional info:

I give this high priority because, if you have a ext2 file system this behaviour
will trigger a file system check each time you reboot the laptop - this is not
