Well, this seems to be a periodic problem on some hardware.  It's an
issue with ACPI.  Some kernels don't work right with some hardware and
don't turn off power to the computer automatically.  Your computer is
completely shut down, it is just failing to turn off.  I had this
problem with the early FC3 kernels on one of my computers.  If you
don't need ACPI, try adding "acpi=off" (without quotes) to the GRUB
kernel line.  This will enable APM, which may succeed in turning off
your computer.
