lo: Disabled Privacy Extensions

You're welcome.

"-1" is the correct value for a loopback device and has the same
effect as "0" (see the documentation above; 1st line "<=0" and last
line "Default -1"). You could try 0 but I doubt that it will make a
difference.

I will install KK 32-bit server edition this weekend to see if I have
the same logging problem. No other ideas, sorry.
