Just for confirmation:
I tried this on my AIX 4.3.1 box (IBM RS/6000 F50, 1x332Mhz CPU, 128Mb RAM),
and it does work.
As the machine did halt, it displayed "888 102 300 0c0" at the front LCD.

You could also recive this data throu the service processor by choosing:
3 - System Information
  4 - Read Service Processor Error Logs

The output I got from this was "<DATE> 1. OS termination string received -
888 102 300 0c0"

A search for this sequence in the IBM APAR database showed that the macine
hanged with a DSI (Data Storage Interrupt). Only god knows what IBM means
with that.
This is the output of the error reporting program:

bash-2.01# errpt -a -l329

Hi,

Local users can halt the operating system by 'adb' command under my AIX
box.

Here's a simple C program:
main()
{
        int i;
        for ( i = 0; i < 10; i++ )
        {
        }

        return 0;
}

I compiled the program and run 'adb':
$ cc -g -o a.out a.c
$ adb a.out -
adb
.main,5:s
a.out: running

Now host halted. AIX 4.2(IBM RS/6000 F50) and AIX 4.3.1(IBM RS/6000 S70)
have 'adb' problem. But AIX 4.3.2 haven't the 'adb' problem. I have tested
it under my AIX box. Is it bug of AIX 4.2, 4.3.1?
