Steve (and a couple others) mentioned a patch for this that's available;
here's a few lines from the README:
Patch-ID# 100116-01
Keywords: spurious level 3 interupt ie1
Synopsis: spurious level 3 interupt for ie1
Date: 06/Sept/90
SunOS release: 4.0.3, 4.1 4.1_PSR_A
Unbundled Product:
Unbundled Release:
Topic:
BugId's fixed with this patch: 1009297
Architectures for which this patch is available: sun3 running 4.0.3
sun3 running 4.1
sun4 running 4.1
sun4/390 running 4.1_PSR_A
ONLY these architectures show the symptoms.
Obsoleted by: 5.0
Problem Description:
This patch fixes a problem which occurs in SunOS 4.0.3 and 4.1
on sun-3 and sun4 gateway machines. When a large number of packets
are being routed through the gateway(ie1 interface), the following
error message will appear in the console window:
vmunix: spurious level 3 interrupt
These messages are displayed as a result of the way the
Intel 82586 ethernet controller works and this patch is
designed to suppress the message.
This really sounds like the fix I need. Why couldn't Sun have told me
this? Grrr.
Several others stated that ie1 was causing the message, that it was
harmless, and could be ignored. That's what I had been doing, but thought
I should at least be brave and try to figure out what was causing it.
Reseating boards and backplane configuration was also suggested by a few
folks and I had tried that earlier. Same thing.
David Classen suggested a Rev. A Xylogics board may be causing trouble. I have
Rev. B which is what cured his trouble. Thanks anyway.
Upgrading ie1 to the new VME based Ethernet board available with the 4/400
series was also mentioned. This may be something to plan for in FY-93.
Anyway, I'm trying the patch first and then talking to Sun about a new
Ethernet board (hopefully under my maintenance contract). Thanks again to
all.
