Description bil kleb 2003-02-23 02:46:15 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003

Description of problem:
After upgrading to the 2.4.18 series kernels from 2.4.9-12
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

Comment 2 Arjan van de Ven 2003-02-23 10:13:45 UTC
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 15:28:41 UTC
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 2003-03-24 03:14:13 UTC
Is there a "step by step" somewhere for trying the aic7xxx swap?

Comment 7 bil kleb 2003-04-04 21:35:16 UTC
Replaced the last piece of hardware: the motherboard, and still
the same "wait_on_irq" oops.  <sigh>
