My highest c/s was 21167.
c/s 21173 is hanging, too (sorry for the delay, but I had to remove my cpupool
stuff due to the scheduler changes for credit2).

Is a call of sync_vcpu_execstate() fro a tasklet really allowed? I don't
think the ASSERTs in __sync_lazy_execstate() are all fulfilled in this case.
