I`ve been able to reproduce the symptom with SMP kernelconfiguration

options        MPTABLE_FORCE_HTT     (enabled)

makes the Swedish Chef module (syncer) gone awry on reboot ie.:

Waituihas jsaf 32582795 erjwefjwhejhrh25 proooces stoop

#options        MPTABLE_FORCE_HTT  (disabled)

gives normal messages during the shutdown sequence

enabling or disabling PREEMPTION / IPI_PREEMPTION  makes no difference.
