ml#STRAY-IRQ
I do apologize to everyone on this list for not thoroughly checking
the FAQ.
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
suppressed anyway.
I opt to live with the warnings and not bother modifying code. My
only hangup is that this problem is a new one since having fixed the
code with the fix from
http://lists.freebsd.org/mailman/htdig/freebsd-questions/2005-April/
084211.html
That fix was in April. I had a solid whole month without any of these
messages, and then they appear right around when I updated my 5.4-
STABLE installation. I suppose the older installs could have
suppressed these messages completely while the new one defaults to 5.
Does anyone have any idea if this is true? I imagine it is highly
possible that it has had the hardware glitches all along and the only
thing that has changed is how -STABLE deals with it.
Thanks for the assistance.
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
meaningless
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
5.4???
