PROBLEM: (82136) (PATCH ID: OSF510-021)
********
  This patch fixes a problem in /sbin/kloadsrv that can cause the /vmunix
  kernel to panic during an installupdate operation.
  The problem occurs when the kloadsrv process is stopped and restarted,
  and all the on-disk files for the currently loaded kernel modules are not
  available on disk.  Once this condition exists, the kernel will panic
  the next time kloadsrv is used to load a kernel module.

  For example, if /var/subsys/lat.mod is a loaded kernel module, the
  kernel will crash if the /var filesystem is unmounted, kloadsrv 
  is stopped and restarted, and a new kernel module is then loaded into
  the kernel.

  Note, restarting kloadsrv while all the currently loaded kernel modules 
  are not available on disk is never recommended.  This patch only prevents
  an immediate system panic for the next kernel module that is loaded.
