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.

Of course. :)  They weren't `stray' by definition otherwise (but
instead, a driver like wdc1 that has no concern with them would get
the IRQs).

Fix your hardware.  Or live with the warnings.  As long as everything
else continues to work, they are nothing to worry much about.

Never trust an operating system you don't have sources for. ;-)

Stray IRQs are indications of hardware IRQ glitches. 
Probably somebody should write an explanation for the FAQ.
