*ouch* shame on me.

I looked at interfaces, links, errors - everything. I found the problem 
in a misconfiguration and you just pointed at it:

The server has not been booted for a few hundred days before upgrading. 
>From an old test there was an "mtu 9000" for the NFS interface still in 
/etc/rc.conf (while it has been reset after failed tests with other 
hardware on that network manually to 1500).

So: SORRY for making everybody mad here. It was just me being blind.

Thanx for pointing me at that!
