I switched my memory chips around and found that one seems to cause more
instability, and removing it made me be able to run that stupid app
"ubench". ;-)

Now I can build several ports in a row without hanging, but I do still
get the odd freeze sometimes. Since memtest86 wont work (on my) A64, is
there something else I can do to stress my memory chips? Which
bench/whatever for FBSD would you recommend to me so I know when/if I
have a stable setup?

I got more or less all available kernel errors, I started listing them
on a postit, from a "GPF" to "freeing membuf twice" but when I had some
10 or so different error messages, I realised it couldn't be the code or
so and went to my hardware. Thanks for you help though.
