And just living with the fact that you have to manually power off your
computer is better than both.  If you just cannot stand that, use a
2.6.8 or 2.6.7 kernel (2.6.8 has some issues with CD burning).  Just
so that it is clear, the computer is completely shut down, it just
fails to turn the power off using software.  It should be fine to just
turn the compter off manually.  But I agree, simply turning off acpi
is a bad option, especially for laptops.  For most desktops, it
probably doesn't matter as much.

I wasn't saying that the announcing brakes the program, there is just
a message printed to the screen upon shutdown saying that the above
mentioned function was called.  Presumably, this always happens, but
because the function is supposed to turn off the computer you never
see it.  Now it doesn't turn off the power for some reason, so you see
it.

Hopefully they will figure it out.
