The power management functions related to interrupts do not know (yet) about per-cpu interrupts and end up calling the wrong low-level methods to enable/disable interrupts. This leads to all kind of interesting issues (action taken on one CPU only, updating a refcount which is not used otherwise...). The workaround for the time being is simply to flag these interrupts with IRQF_NO_SUSPEND. At least on ARM, these interrupts are actually dealt with at the architecture level.
