In the first case, the answer to the ping came 86 ms after the ping was
sent.

In the second one, the answer came before the question... you've probably
found a hole in the space-time continuum :-)

It must be some timing error in your system, you of course can't get
negative times for a ping.

yea, there is a patch from AMD to fix the negative value. it's surprising
to know it is not the nic...
