5.22. What does "stray IRQ" mean?
Stray IRQs are indications of hardware IRQ glitches, mostly from
hardware that removes its interrupt request in the middle of the
interrupt request acknowledge cycle.
One has three options for dealing with this:
Live with the warnings. All except the first 5 per irq are
Break the warnings by changing 5 to 0 in isa_strayintr() so that all
the warnings are suppressed.
Break the warnings by installing parallel port hardware that uses
irq 7 and the PPP driver for it (this happens on most systems), and
install an ide drive or other hardware that uses irq 15 and a
suitable driver for it.
IN the 4.x versions of Freebsd
isa_strayintr lived in /usr/src/sys/i386/isa/intr_machdep.c
It was my understanding this code was fixed in 5.x so that this
message would not happen again.
In 5.4 there is no intr_machdep.c file any longer.
Does anyone know where the source of this message is located in
