PROBLEM: (82509) (PATCH ID: OSF510-043)
********
  This patch changes the kloadsrv and hotswapd entries in the V5.1 
  /etc/inittab file.   Without this patch, a system that is shut down to 
  single user mode and then booted back up to multiuser mode, may have one 
  or more of its dynamically loaded kernel subsystems be in a state where  
  they can never be unloaded.   Also, none of the symbols in those subsystems
  will be available to any subsequently loaded kernel modules.
