This is my first time trying to report a kernel problem, so I have no
idea if I'm doing it the right way or not. I also don't understand
the problem; maybe it's my own fault. Here it goes, though:
[1.] One line summary of the problem:
spurious 8259A interrupt: IRQ7. (during heavy disk reads)
[2.] Full description of the problem/report:
I was experimenting with kernel 2.5.25 with 2.4 IDE forward port and
Toshiba ACPI extensions. I was running find and part way through I
got this message on the console:
spurious 8259A interrupt: IRQ7.
It doesn't seem to be reproducible.
[3.] Keywords (i.e., modules, networking, kernel):
spurious, interrupt, IRQ7
[4.] Kernel version (from /proc/version):
Linux version 2.5.25 (root@zigoku) (gcc version 2.96 20000731 (Red Hat
Linux 7.3 2.96-110)) #1 Tue Jul 30 01:31:34 PDT 2002
[5.] Output of Oops.. message (if applicable) with symbolic
information
resolved (see Documentation/oops-tracing.txt)
No oops.
[6.] A small shell script or example program which triggers the
problem (if possible)

There were a discussion about this warning some time ago.
As far as I remember, it's just a interrupt which is not registered by
any peripheral.
this is not a kernel bug, just a buggy hardware.

OK -- I'll take that explanation. I mentioned it because it happened
in the first half hour of using this kernel specifically, and I'd
never seen it before.
Thanks,

I only see this if I have IO-APIC turned on for a uniprocessor
system.

FWIW, I don't have IO-APIC turned on (and didn't before either)
