I have noticed that it exists.  Not sure it would help with the issue I was 
looking into.

I have determined that I would see:

CPU5  841028423232 (+    3900)  hpet create [ tn = 0, irq = 0, delta = 
68718266336, period = 1000000 ]

If I had been able to reproduce my issue.

Do I need to make a change there also?
