It has a rather high trigger rate, but only a plus designator.
Could be USB related as, of course, it has network traffic.
However, the interrupt 17 is listed in the DMA controller:
bcm_dma0: <BCM2835 DMA Controller> mem 0x7e007000-0x7e007eff irq 4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19 on simplebus0
70, which has a rather low rate, isn't listed in dmesg at all.
devinfo -rv doesn't list Interrupt 17 at all.
It does list 0x17 for uart0, but uart0 shouldn't have a high rate and I
assume vmstat -i to list decimal interrupt numbers.

This is on a Wandboard-Quad:

Also some mysterios plus interrupts, but non with such a high rate.
