I had a re(4) card that did crash 7-stable now i cvsuped to 15-07-2008 and did a rebuild

The system is now in "production"  and I see the following in /var/log/messages.

It is a small intranet webserver and does cacti and nagios things and mirror cvs for the other machines.

It also not always load ok on a reboot !
Sometimes it complains about something with PHY
A reboot than fix this and loads the re0 driver.
