The dom0 kernel spits out messages like the following starting around the
init of cpu1 time, and periodically thereafter.

Timer ISR/0: Time went backwards: delta=-50206266948 delta_cpu=13733052
shadow=8186343367 off=13649733458 processed=72042343367 
cpu_processed=21822343367

Eventually just hanging (or making such slow progress to be
