Thanks a lot!  I really = appreciate the help!  I recompiled and everything worked out = great.

 

Does it run into that error = simply because the board doesn’t have a parallel port?

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] <=3D 5)

 

To  this

 

      if (intrcnt[1 + intr] <=3D 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.
