It might have been consistently wrong though (how would I figure this out?). The symptom I've observed is that qemu reports the first instruction of the basic block rather than the exchange itself. If you "x/10i <fault eip>", you should see an xchg before long. Either way, sounds like a qemu bug which should be reported to them.
