badness in umount? FC4

[Hugh Caley]

I have just installed FC4 on an older machine and I seem to get a kernel 
error when a umount is done by the automounter after a user logs out:

Nov 22 18:53:30 tdb3 su(pam_unix)[3502]: session opened for user mganes 
by (uid=0)
Nov 22 18:53:35 tdb3 su(pam_unix)[3502]: session closed for user mganes

(automounter unmounts home and other directories)

It doesn't seem to be panicking; just this dump.  Seems to happen every 
time.  This particular user gets about 5 mounts whenever he logs in, but 
it did the same thing for me and my login only mounts my home directory.
