No shutdown & reboot

[jdbca at clix.pt]

   I am running FreeBSD 7.2 - stable and update regularly.
   Following a recent update, I am now unable to shutdown or reboot my
   compute= r
   using "reboot", "shutdown -r now", "halt -p" or "shutdown -p now".
   This has always worked before.
   Instead of shutting down or rebooting, the computer appears to halt,
   and st= ops with the
   "uptime" message. There are no error messages.
   Cheers
   DuncanB
