Here is the additional information on ETIME and the hanged Ippon UPS.

I've been doing some extra tests with the Ippon Back Pro 700 device on the
Scientific Linux 4.8 and it turned out that it is typical for the SL4.8 kernel
to return ETIMEDOUT (-110) error instead of ETIME (-62) when trying to
communicate with the hanged device.
Looks like ETIME had appeared in the linux kernel some time between 2.6.9 and
2.6.26 and ETIMEDOUT was used for such error before the introduction of ETIME.

Now, back to the FreeBSD. I had finally read up the FreeBSD handbook to the very
end and I am almost ready to give the freebsd installation a chance. What
versions of the FreeBSD are considered to be "current" from the NUT perspective?
