ps -axf # to figure out what process is hung
# take the process id from the ps listing and
kill -HUP <pid>

for example:

# ps -axf | tail -3
  944 tty1     S      0:01 login -- rusty    
 2184 tty1     S      0:00  \_ -bash
 2195 tty1     R      0:00      \_ ls --color=auto -F -altR
# kill -HUP 2195

If the HUP does not do it, try progressivly harder kills till you
reach kill -9.  If -9 doesn't do it - nothing will.  (And, no,
counting from 15 down to 9 does NOT count for progressivly harder kills ;-)
