Stray irq 7 messages
 
The FBSD FAQ says
 
5.24. 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.
 
* 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.
 
 
 
To stop the annoying bogus stray irq 7 messages you can hack the source where these messages originate from and change the counter value 5 to 0 so the messages will no longer be issued.
 
isa_strayintr lives in  /usr/src/sys/i386/isa/intr_machdep.c  
 
cd /usr/src/sys/i386/isa/
cp intr_machdep.c intr_machdep.c.org  # make bkup of original
ee intr_machdep.c
 
 
Find isa_strayintr to locate start of stray irq 7 logic
 
change this
 
      if (intrcnt[1 + intr] <= 5)
 
To  this
 
      if (intrcnt[1 + intr] <= 0)
 
 
Recompile your kernel source and those stray irq 7 messages are gone. Document this some place for your self just in case you reinstall from cdrom.

Subject: Intel SCB2 Server w/ FBSD 4.5
 
Hey Everyone,
 
I was curious if anyone has had any problems with the Intel SCB2 boards in FreeBSD.  I got a dual board, case, the whole works for the most part from Intel and put FreeBSD on it, no problems there.  (I figured that there might be with the hot swap drives and all, but to my surprise, everything was fine.)
 
The only real problem, well, ‘bug’ that I’m noticing is after boot, I get a bunch if “Stray IRQ 7” messages in the logs.  
 
I checked over the system, bios, scsi controller (Adaptec AIC7899), and none of those have anything on IRQ 7.  I checked out the dmesg.boot and the only thing I can find even close to 7 is:
 
ahc0: <Adaptec…blah blah> port … mem …. irq 3 at device 7.0 on pci1
ahc0: <Adaptec…blah blah> port … mem …. irq 9 at device 7.1 on pci1
 
Thanks in advance for any help on this!
 
Thanks again,
Adam
