Well I tested something different.
This is a (older) dual opteron 244 system. So each chip has only one core.
And I removed one of the processors...
It just runs without any problems as far as I could test.
With 2 processors it is just enough to let init start all the nfs related
stuff in /etc/rc.d and lock up the system.
So I guess we need to look at totally different things.
Given enough time, I'll check and see whether 7.x does run without trouble.
If somebody thinks this thread should go to amd64, just say so.
But I am running the i386 stuff.
dmesg and stuff in http://www.tegenbosch28.nl:/FreeBSD/toy
(although I see I have to fire up the system again to get a correct dmesg.)
