Perhaps jitter has no effect to the issue. I've upgraded to 2007.12 recently
and problem persist. It's annoyed me a lot. Then I've decided to explore the

I'd login thru ssh. I have turned ts-adc driver debug mode on and found
interesting things.
Following is normal behaviour with low or even no load.
