I ran memtest for 11 hours and it completed 4.7 passes with no problems.
But then memtest is about cpu and memmory interaction. If the problem is 
disk related there is also disk/chipset/dma and memmory interaction. I 
could degrade my system by turning dma on disk io off, or i could have a 
closer look at kvm-autotest.
