Description of problem:
I am running rawhide, kernel 2.6.10-1.1126_FC4 and also
When NetworkManager has made a connection, then when I try to stop
iptables (process 1), it hangs on "modprobe -r ip_tables". If I stop
NetworkManager (process 2), then the "process 1" continues and stops.
I can start and stop iptables as long as NetworkManager is stopped,
or has not yet made an active connection. When I start NetworkManager
and make an active connection, I also can not start iptables.
Only message I get when I try to modprob -r ip_tables by hand when
NetworkManaager is working and active:
FATAL: Module ip_tables is in use.
The behavior that is expected (start/stop iptables with active
NetworkManager connection) works for kernel 2.6.10-1.1115_FC4
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have NetworkManager started and have an avtive connection
2. execute service iptables stop
3. wait forever
Actual Results: system is hung waiting to terminate iptables.
Expected Results: iptables should be terminated.
I can not really tell if this is a NetworkManager bug, but since it
works with other kernel revs, I think it is kernel related.
