Sorry for the late summary as i just got to do the CPU testing on
customer's site. Actually, the problem was due to customer's application
shutting down very, very slow ( takes about 5 minutes) which i could
monitor from command line shutdown. If shutdown from CDE, it would went
into blank screen and the OK prompt only appeared after the application
have shutdown properly.
Special thanks to :
