I am having the similar issue. Random "system" cpu ramp ups to 10-20% of my Core i7 920 system.
I have attached a trace though I don't know how this trace really works. I don't know if it is valuable because I am not sure if it was running while I was lagging. Let me know what you think thanks!

EDIT: I have posted a second trace which I assume has data from when it was lagging here: https://dl.dropboxusercontent.com/u/66927202/DPC_Interrupt2.zip
