Public bug reported:

Picked up a HP laptop during July sales, and found the CPU soars to 80+ with 
kacpi_notify hitting GPE17.
I would like some help finding the cause.  Google searches were vague about 
masking the interrupt which did NOT help.  If we can find what is calling the 
interrupts maybe we can better document a solution.
