Are you sometimes using MGR as root? MGR leaves a junk entry in file
/etc/utmp (the file where all currently logged-in users are kept).
This entry states that root is still logged in on /dev/ttyp0.
When you want to shut your system down reboot/shutdown/halt will try
to write a warning message to the control terminals of all users.
As /dev/ttyp0 is not opened for reading any more shutdown will block
when it tries to open /dev/ttyp0 for writing. However you should be
able to interrupt shutdown by pressing CTRL-C at least.
