Does not boot far enough to have an environment.
>Description:
      5.3Beta7 hangs right after displaying the system memory information. I'll guess that the 2-CPU motherboard, when there is only one cpu installed, is confusing the SMP probes.

The Tyan S1668 motherboard is rather old (circa 1996), but it still runs FreeBSD 4.3 just fine. Only when I try to boot 5.3 from the three boot/kern1/kern2 floppies are there problems.

Here are the verbose boot messages. It does not continue after the "avail memory" line.

If there is anything I can do to gather more data for you let me know.  Otherwise I'll try again with the next 5.3 release.

      Tried multiple times and each time it hung at the same place.

State-Changed-Why:  
I am currently trying to determine the exact problem with the 
submitter. 

This is the final line of his bootup sequence: 
Timecounters tick every 1.000 msec. 

If i refer to my personal system i can see that after 
that the harddisks are probed.  So something might be 
wrong there.  Let's exclude that and try starting 
without ACPI to see what that does. 

Place the PR in feedback mode till the problem is more 
clear.
