The issue I have seen was on two boxes with 890FX chipset and Phenom II X6 CPUs on a recent avi/master which was 2.6.36 + some kvm patches.
The problem was that the box became extremly sluggish and slow. I stated dstat and it reported a lot of missed ticks. After some time the clocksource tsc became unstable and the system became responsive again. I have not yet investigated this further but can do any requested tests.
