CVSup started at 0347 hrs. Pacfic Daylight (7 hrs. west of GMT/UTC)
from cvsup14.freebsd.org. Build/install/mergemaster was uneventful.
Reboot after mergemaster proceeded as if nothing strange was about
to happen, then (cut/pasted from serial console):

This is my SMP (2x866 PIII) build machine.
Anything else I can do to help figure this out?
Thanks,
