Halted system won't halt

Halted system won't halt

[David Newall]

I've got a remote machine running ubuntu 2.6.24-19-generic which I ssh
into.  When I said "poweroff -f -p" it strangely came back after a few
seconds.  Perhaps my banging on the keyboard made a difference.  The
same thing happened when I said "halt -f -p".  Sounds like user error to
me, except the log file shows kernel halt messages.  These are the last
n lines logged:

I can't explain that.

A surprise to me; yes, the kernel is configured for SMP.    (The
hardware isn't.)  I can't find the patch.  Got another hint for me?

Thanks.

If hardware is UP, patch is nop :-(.
