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.
