I had multiple guests  (from which also multiple (1 PV, 2 HVM) use pci 
passthrough (with one or multiple devices each)), running at the same time.

This occurred with all my guests up and running for a short while after host 
boot .. and pci passthough working (verified that). 

Wasn't doing anything special i can point out .. 

If it still helps i could try Andrews suggestion and try out with only commit 
aeeea485 ..
