Just as a final report after ordering some more memory and running 
MemTest86+:
   The A slots of the bus connected to the second CPU generate seem to 
be broken.

Filling any of those slots will generate memory errors.

One thing I'm going to do is reseat the CPU, and see if any of the 
flatbed pins is perhaps
skewed or something of that nature.

Sad thing is that the kernel is not able to report this and perhaps 
panic or the likes.

But I must say I've again learned lots of nice things about kernel stuff.

Thanx for all the support here,
