> what irq information for re0 is listed when you do "vmstat -i"?

I get this one:
 $ vmstat -i

Is there any problem here?

Yes, at the beginning of this year.  Without much success.

I tried these the past, but don't remember this solved anything.

Since it is a notebook, i didn't get any diode on the ethernet adapter.
Just get one on the network switch.

When booting and before loading the kernel i get a green light (there is
a link and is ok).  During the load of the kernel, the diode gets orange
(there is a link but something is wrong).  When starting the DHCP client,
the light symply disappeared.  After tens of second (~one to two minutes),
the light reappeared and become green.

Also tried this using '/etc/start_if.re0'.  Same problem here.

Thanks,
