I'm trying to get FreeBSD 5.2.1 going on an older thinkpad laptop.  The 
install went smoothly from floppy and 5.2.1-RELEASE CD.  Now I'm trying to 
do an installkernel and installworld from an NFS mount on my main machine.

I did the buildworld and buildkernel on the faster machine, with these make 
flags on the command line:
MAKEOBJDIRPREFIX=/usr/obj/586
KERNCONF=TP365XD
CPUTYPE=i586

When I try to do an installkernel and/or installworld, install crashes with 
signal 4.  If I'm not mistaken, signal 4 is an illegal instruction.  What 
could be going on here?

I've used this procedure on other (somewhat newer) 586-class machines 
without problems.  Is this a bug, am I doing something wrong, or is the CPU 
in this laptop not fully 586-compatible?  Dmesg (from the currently 
installed GENERIC kernel) says:
CPU: Pentium/P54C (119.78-MHz 586-class CPU)

Should I try CPUTYPE=i486?  What else can I do to track this down?

Any input appreciated.  Please CC me.
