Could you follow up on Frederic's detailed tracing suggestions that would give us the source of the latency?
( Also, as per lkml etiquette, please try to keep the Cc: list intact when replying to emails. I missed your first reply that you un-Cc:-ed. )
A quick look at the latencytop output suggests a scheduling latency. Could you send me the kernel .config that you are using?
