ic5141 analog enviroment frozen

ic5141 usr3 was installed on RHEL AS 4 update 8, when i try to bring up the analog enviroment, it is just frozen and never opens up, any one have idea? by the way, when intalled on RHEL AS 3 update 6, there is no problem. i did try to reinstall redhat and ic5141, it looks like problem solved for the 1st time, but it comes again later on after i did some setup on my intermt.

May be you have brought all the network interface down. You may use "ifconfig" to check if interface "lo" is up.

i use "ifconfig" and got the following, could you see any problem?
