 This is expected behaviour. Have you tried 'halt -p'? From the man page:

   -p      Attempt to powerdown the system.  If the powerdown fails, or the
           system does not support software powerdown, the system will halt.
           This option is only valid for halt.

 Cheers,
 Jared

 No, it's not.  The submitter clearly stated you don't get the delay with
 a non-acpi kernel.

 And that's normal. As soon as we take control over the soft power button 
 (by entering ACPI mode), this is how things work. A short press generates 
 an interrupt, and a long press bypasses this mechanism and powers off the 
 machine directly. Since the kernel is already halted at this point, 
 we can't really handle it.

 If the submitter didn't first run 'halt', he could have pressed the power 
 button and the system would have gracefully powered off on its own.

 Cheers,
 Jared

 The hardware is designed to work this way.

 Then don't call it expected behaviour, call it an expected bug.
 I certainly don't expect it and frankly it annoys me if I accidentally
 mistype halt without -p and am not quick enough to tap the power button
 before the kernel halts.

      Personally, I don't really care about this issue, but would it be
 possible to "shutdown" ACPI when the system is halted or tell the BIOS
 that we no longer wish to handle the power button?
