Description of problem:
All the problem described below work well on 2.6.9-1.667.

Few months back I had this problem when I upgraded to 2.6.10-1.776 from 2.6.9-1.667. I got help from a LUG and stopped cups by "chkconfig --del cups".

Now I see that the problem is (dont know if it is the same problem) in different places. For example - 

a) The system hangs when I start cups by /sbin/chkconfig --add cups

b) The system hangs when I click on (I have GNOME desktop) "Applications->System Tools->Network Device Control".

c) The system hangs when I click on "Applications->System Tools->Internet Configuration Wizard"



Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Boot the system with kernel other than 2.6.9-1.667 (I have 2.6.10-1.776, 2-6-10-1.770, 2.6.11-1.14, 2.6.11-1.27)
2. Either start a) b) or c) above
3.
  

Actual Results:  The system hangs - the keyboard does not respond.. the mouse does not respond..
Only way to get out of this situation is to reset the PC
