Yes. I don't know if its a specific Athlon XP related problem as I did
observe a similar post some years ago. And, Apparently its the same
In this case its the installation. In my case its after the installation.

Maybe its something in the BIOS, but the thing is that Linux boots
fine on the machine. Maybe some driver is crashing and is causing a
reboot of the machine. Are there any critical drivers in the system
that can result in such a problem.

I can install it just fine, but can't seem to to boot into the
installed version (Once its been installed).
I did create the FreeBSD swap partition before the root file-system
(and it still seems to label the root file-system as 'a'), Would this
affect the system boot up in anyway ?
