you people you!

FreeBSD www1.cdn.sjc 5.3-RELEASE FreeBSD 5.3-RELEASE #1: Mon Nov  8

IBM e325 dual proc 4GB ram -

msi-9145 mainboard

i HAVE seen it, along with top/iostat no longer reporting any cpu 
activity (everything is 0%, activity and idle) a couple of times.  this 
was on a system that was under pretty heavy load, and had been cvsup'd 
from a BETA release to current (all correct make/mergemaster commands 
followed).  after a reboot, both issues go away.
