Log message:
Rate limit messages about spurious ISA interrupts on yeeloong systems.
On suspend, the USB driver is put to polling mode and it no longer
claims interrupt requests. If the USB controller keeps raising new
requests faster than spurious interrupt messages can be printed,
interrupt processing hogs all CPU time and the suspend code gets
stuck. The rate limiting should prevent this from happening.
