That's "calcru: negative time" -- an error message that
(unfortunately) shows up for any number of reasons.
Often the cause is buggy hardware, but sometimes it can be a software
problem.
For example there's:
http://groups.google.co.uk/groups?hl=3Den&lr=3D&ie=3DUTF-8&oe=3DUTF-8&s=
afe=3Doff&threadm=3Dfa.g80oftc.186qv3o%40ifi.uio.no&rnum=3D7&prev=3D/groups=
%3Fq%3Dcalcru%2Bnegative%2Btime%26hl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8=
%26safe%3Doff%26sa%3DN%26scoring%3Dd
However, unless you're doing some sort of specific action that
triggers that particular case, that is unlikely to be the root cause
of what you're seeing.
See microtime(9) for an explanation of where this comes from. The
solution given there, ie:
# sysctl -w kern.timecounter.method=3D1
is a good thing to try first.
Cheers,
Matthew
