Description of problem:
After upgrading to the 2.4.18 series kernels from 2.4.9-12
our http://supermicro.com/PRODUCT/MotherBoards/RCC_LE/370dl3.htm
dual Pentium 3 machine has been leaving 'wait_on_irq' oops in the
logs for both processors, the ksoftirqd_CPU[0-1] processes have
been racking up abnormal quantities of time, and the machine will go
unresponsive to the keyboard for tens of seconds at a time.

We've swapped out the CPUs, memory, broken an IDE software raid,
and tried various kernels in the 2.4.18 series (currently running
2.4.18-24.7.xsmp) all to no avail.

How reproducible:

Steps to Reproduce:
1. shutdown machine
2. reboot

Actual Results:  If one waits for about a hour, things start going south in terms of
keyboard responsiveness. Then every few days it'll drop an oops
in the log and the keyboard responsiveness will progressively
get worse.

Expected Results:  No hesitations or oops

can you post a dmesg of the machine ?

dmesg w/o an oops

The machine's only been up 12 hours and hasn't lobbed an oops yet.
Comment 4 Arjan van de Ven 2003-02-23 10:28:41 EST
one interesting test would be to use aic7xxx_old instead of aic7xxx
2.4.9 used the old driver by default

A dmesg after a longer period of uptime

Here's a dmesg after 3 days worth of uptime
and we now have

 54:13 ksoftirqd_CPU0
 66:58 ksoftirqd_CPU1
Comment 6 bil kleb 2003-03-23 22:14:13 EST
Is there a "step by step" somewhere for trying the aic7xxx swap?
Comment 7 bil kleb 2003-04-04 16:35:16 EST
Replaced the last piece of hardware: the motherboard, and still
the same "wait_on_irq" oops.  <sigh>

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
