>Organization:
Digital:Convergence
>Environment:
The hardware is a Compaq DL360 with 4GB of RAM and 1 800MHz PIII
processor.
I downloaded a 4.1-STABLE snapshot iso file, 20000922 to be precise.
I created a CD, and attempted to boot from the CD.
The log shows:
FreeBSD/i386 bootstrap loader, Revision 0.8

>Description:
there were some commits for new pmap and vm stuff
between 4.1-RELEASE and 4.1-STABLE-20000922.
>How-To-Repeat:
Boot 4.1-STABLE with 4GB RAM installed.
>Fix:
Remove some RAM. The system booted correctly
with 3GB RAM installed. 4.1-RELEASE boots
just fine with 4GB RAM installed.
