:    There is another possibility... it could be actual bad memory,
:    or bad timing if you've accelerated your cpus.  Try shifting
:    the memory around and detuning the cpu frequency or FSB frequency
:    if the BIOS has the ability to do so.  I only give it a 15% chance
:    of being the issue.

    Never mind on the bad memory possibility... I just reproduced it on
    my test box using a vkernel -n 8 and a buildworld -j 8.
