I just tried testing tip of kvm.git, but unfortunately I think I might be hitting a different problem, where processes run 100% in kernel mode. In my case, cpus 9 and 13 were stuck, running qemu processes. A stack backtrace for both cpus are below. FWIW, kernel.org 2.6.32-rc7 does not have this problem, or the original problem.
I just posted a patch fixing this, titled "[PATCH tip:x86/entry] core: fix user return notifier on fork()".
