Hi
Every now and then a mail or PR pops up with this question.
I search the FreeBSD web pages for info about this but did not
find any, maybe I just missed it.
I suggest the following is added to the faq
=============
Q: What does 'stray irq' mean?
A: Stray irq are interupts from some hardware that do not have
a driver assigned to it. J Wunsch writes in a response to a PR
"Stray IRQs are a known phenomenon. Obviously (if you think
about it :), there's nothing the kernel could do about it.
Unless you have misconfigured your kernel so there's no driver
assigned to a device that actually issues IRQs, they are a sign
of flakey hardware, often caused by glitches on an IRQ line."
You have three choices:
1) Live with the warnings
2) Get a driver for the hardware into your kernel
3) Remove the hardware that generates the interrupts
