I dug a little more and found out some new info.
Unsolved bugreport with same symptoms:
http://marc.info/?l=linux-kernel&m=119613299024398&w=2
Problems appear if I start br0 interface, as context switch rate
increases 200 times. If I start eth0 instead everything looks ok.
The bugreport above had bridging enabled too.
When using eth0 I get:
vmstat -n 1 10
