Oh, nice it was only configuration problem. I wish I had such
problems, they're so easy to fix, hehe. The problem with I/O
(specifically network I/O) I have for a long time is that mouse will

transfer is happening over the 100Mbit interface. Fxp driver and SMP
system if that matters. No cure in the sight.
