Looking at the code, there are only three ways to not get the "up"
print: (1) up less than one minute (not the case), (2) boot time is
Jan 1, 1970 (unlikely), or (3) sysctl() fails (also fairly unlikely).
Can you run it under ktrace (ktrace uptime; kdump | less) and check if
the call to sysctl is failing? There should be one call fairly early
(before it opens utmp or utmpx) which is irrelevant, and one near the
end, which is the important one. If that's failing, the question is
Also, check the boot time in case that's 0. If so, the question is
